Squeezbox 2 or 3?

Well, I found my answer on the Squeezebox differences for anyone who is wondering the same question:

I like the form factor of the version 2 best. I'm limited on rack space and it will work best. Other then the form factor, it looks like version 2 and 3 are functionally identical. Can I assume that the display options are identical as well?

I still need to decide if I should scrap the Airport Express for it. How is the Squeezebox SW compared to iTunes?

Thanks for the reply,

Did the mods make a big difference and what were they? Again, I'll be going through the Arcam's DACs. I'm sure a new, beefier power supply will help. Also, since I'm using all of my Arcam's coax digital inputs, it looks like I'll have to go optical with the SB2. I have an extra Kimber Opt-1 for that which should be OK. I notice that I can't use music downloaded from Apple. No big deal there for me though because I can't convert those files to Apple Lossless anyways so I'll get my music elsewhere.

Thanks again for the input.
