Jim, after seeing your earlier post, I understand that you dont want to wait as there is always something "better" coming along. I played that game for almost 2 years before my purchase.
Since you are going to control room lighting and may want to take advantage of some model close outs before the new stuff comes out this spring summer, I would suggest the Panasonic Plasma (either of the consumer models 60 or 600 series). Its a great display and more bang for the buck compared to Pioneer.
If you want to look at a 1080P display, then check out the Sony SXRD 60" or 70" XBR2...not the A2000 ( an ISF calibrator told me the video processor on the XBR2 is superior to the A2000).
We sit 14 ft from a 61" 1080P set in a room approx 12x16' and could have easily gone with a 70"set
