I just went with this system:
Sony TV FWD-50PX1 50" Plasma 16x9 aspect ratio HDTV Monitor
Wall Bracket for Sony 50" Plasma TV
Philips TSU7000 Color LCD Touch screen Universal Remote
Sony Receiver STRDA3100ES 120watt x7 Surround Sound, Digital Drive
Sherbourn Amplifier 2channel (this amp is to power zone 2 Spks and vc's)
Sony DVD Player DVPCX985 400Disc Progressive, SACD, CD, DVD Player
Use existing CD player and Cable Box
Polk Audio Center Spk RMSeries Dual woofer Single tweeter
Polk Audio Inwall Spk RC65i Single 6"woofer, Single 1"tweeter
Speakercraft IR Repeating System Eye, Brain and Emitters (Plasma Proof)
Newpoint Surge Protector 8plugs
Elan Volume Control VSW Impedance Matching (new vc's for the spare rooms)
I have the same Sony in a 42" in my boat, best features for me is the viewing angle and the picture clarity under differing light conditions.
If you have the room for it, Sony makes a rear projection WEGA HD that is 16" deep, I have the 50" model and love it. It is very close to the quality of the plazma and only about $1,500.
