Help Soon - Martin Logan surrounds


Help I'm signing a H.T. contract this week.
I have Martin Logan SL3's L/R.
Just bought a M/L Theater Center speaker. OMG it's great.

Multipurpose room with projector (soon).
Room is 24'W x 33'L x 8'H. and I need to designate surround speaker that will complement the Martin Logans. Running on B&K Ref 30 with B&K 7250 Amp.

Need speakers that are accurate with fast response. (That's what Scottie from M/L just told me to ask for. He even gave me this site. What a guy)

Budget $500 to $600. Can I do it........ Help. Thanks

Just a follow up. The Energy Veritas 2.2's worked out VERY WELL in my theater set up. Some will say use ML surrounds or nothing, but they obviously have dedicated rooms or dont have wives who care about having company over. The 2.2 are very nice looking in black.
I have ML Scenarios for my surrounds, and of cousre they work well with the Odyssey/Cinema fronts. However, I disagree with the claim that ONLY MLs work well - my previous surrounds were Triad Silvers. They are dipole cone speakers that are designed for in-wall mounting. They worked a lot better than you'd expect from all the discussion, with both my previous Aerius i's and the current Odysseys. Note that this for HT.

Matching for HT is, in my opinion, overemphasized, because on HT there is frankly little to choose from between the Scenarios and the Triads.

However, I do have a little bit of surround music (several DVD-As and a handful of SACDs) and there the difference is much greater. For surround music I might well agree that only the MLs will match ML mains.
