Affordable "Thiel type" speakers are?

Thanks Unsound, just what I would like to have, but I'm afraid of shipping damage even if in original boxes. If they were within 250 miles of me I'd be picking them up this weekend!
Thanks also Steuspeed, but I've been doing the national Craigslist search for months. One would think some would have been listed, but none have been so far within 250 miles of Daytona Beach.
I do know of some Revel F 50s within driving distance, but they can't be auditioned so I'm not sure if they would be a clear step up from my 3.5s in detail, transparency and bass taughtness.

Thanks All for the ideas,
I have been a transparency and detail guy since 1992 when I got my Apogee Slant 6 speakers. In '95 I bought some Vandy 2CEs for a secondary system and liked them a lot, but in comparison with the Apogees felt they were somewhat veiled and a bit less detailed.
In 2011 I ran into a very good deal locally on some Thiel 3.5s and decided to take a chance on them based on their reputation, even though they sounded mediocre in the seller's mid-fi system. I was somewhat surprized and pleased that they sounded more transparent, detailed and had tighter bass than my Apogees. The only problem was that they seemed a little bright at first and required upgrading my electronics to sound really good. With a Threshold pre and C-J 2300A amp feeding them they were a big step up from my previous system. Out of curiosity, I did try out the Slant 6s and 2CEs with the new electronics and did feel that while both responded very nicely, I still preferred the 3.5s by a good margin. At this point decided that I liked the Thiel "house sound".
Shortly after this I converted a little used TV room to a "man cave" and moved the audio system there. Looking for even better sound there, after getting much help form Agoners, I bought some new Thiel 2.4 demos at a great price and moved the 3.5s into the bigger room which has now become my secondary system.
Hence the original post looking to improve the sound in that room. What I was wondering about, since I haven't located any 3.6 Thiels, is whether I had other good options given my listening tastes. I am a big believer in buying used and don't want to audition something at a dealer if I know I am not going to buy there so I lack info as to what other possibilities there might be.
There have been advances in speaker design since the 3.5s came out and who knows that the Vandy 3A Sig does not have more of what I am looking for than the 3.5s do. I don't feel that my 2CEs do, but that too is an older design. Stereophile rates the PSB Synchrony 1s class A, but do they have more transparency and detail than the 3.5s? I don't know. So, given the helpful insights I have been given here in the past, I posted looking for suggestions from folks who were familiar with the Thiel sound and were aware of other affordable options that I should consider. Perhaps I should have listed the subject as "Affordable options to Thiel 3.5s which would be a step up in detail, transparency and bass taughtness". Anyway, given this clarification of what I am looking for help with, does anyone have any thoughts to share? My secondary system electronics are ARC 14 pre and Hafler 9500 power and I recognize that I will probably need to upgrade the Hafler to get the best out of anything that is a step up from the 3.5s. And yes, I realize that the 3.5s would improve with better amplification, but they can't catch the 2.4s since I have compared them in the same room with the really good electronics.
Thanks in advance,

Hi Stevecham,
I am not looking for a step up from the 2.4s in my main system. I am completely satisfied with them and prefer their bass to the 3.5s overall because it is tighter and more defined, although the 3.5s do go deeper. What I am trying to get info on is affordable, step up, non-Thiel speakers from my 3.5s, not the 2.4s. I am only asking this because I can't afford another pair of 2.4s and have not been able to find any 3.6s within 250 miles. My latest post was a bit long winded but it gives the background on my situation including the amplification used in both systems.
Thanks for the interest

Hi Unsound,
I totally respect your opinion and you are a gentleman whose inputs in past posts have helped me a great deal in getting my main system to the point I am truly happy with it. What I personally prefer most in the 2.4s over my 3.5s is the detail. I notice more of everything from top to bottom in a recording with the 2.4s and do not feel that this is due to frequency response issues. As Gary at Thiel says, "2.4s reveal everything in the recording whether you like it or not."
I see that a legitimate point of view of this could be that the 2.4s have crossed the line from wonderfully detailed into being "clinical or hyperarticulate". I certainly don't feel my 3.5s are lifeless or homogenized, so it seems perfectly appropriate to describe them as more coherent. As you point out it is a matter of personal preference.
If I run across some affordable Audio Physics I will certainly try to audition them since their design philosophy suggests they might have a lot of the 2.4 characteristics that I like, but my intuition tells me moving to Thiel 2.3s, although a worthy suggestion, would feel like a lateral move.
Based on all the input so far it appears that my best bet is to be more patient and just keep looking for 3.6s, which from all I've read, are somewhat more detailed than the 3.5s. I am, however, still open to any other suggestions.
Thanks to All

Thanks Unsound, for the Ebay lead.
Unfortunately, over 400 miles and 6 hours drive time one way to Stockbridge Ga. is too much for this old guy. I'll go up to 250 miles if I can find some that look promising, but that is about my limit. I have decided though, that unless I run into some Audio Physics close by to audition, I'll just be more patient and watch for 3.6s. It is not as if I am unhappy with my 3.5s, just looking for a bit more. I am within easy driving distance of Orlando and Jacksonville and could stretch myself to the Ft. Lauderdale, Miami area so it isn't as if I'm in the middle of North Dakota.
BTW to the Vandersteen fans who have responded, I like my 2CEs a lot and do feel they do a great deal of what the Thiels do. My preference in no way suggests that I think the Thiels "blow away" the Vandys. I have a suspicion that Jim Smith of "Get Better Sound" might suggest that I have an excessive focus on "audiophile sound effects" which detracts from my emotional connection with the music. Vandys are a top shelf speaker in my book, as are the Apogee Slant 6s which I still have. I have to move some speakers out of the house, but all of them are so nice I hate to see any of them go.
Thanks to everyone for the inputs, I do feel clearer about my options and for now I'll opt to watch and wait for 3.6s.
