The upgrade bug has bitten once again. Sometime between now and the end of the year I plan on purchasing a large (55"-65") HDTV-ready RPTV to replace my 32" WEGA. I'm considering the following models: Sony KP-65WS500 Toshiba 65H82 Mitsubishi WS-A65 Samsung HCM-5525W I'm looking for recommendations and opinions on the above units, or others in the same price range I may have missed. It's been a long time since I've evaluated projection televisions. This one will be used primarily for progressive-scan DVD viewing in a 15'x28' room at a 10'-12' distance. From what I understand several manufacturers have made it impossible for consumers to access the service menu on their TVs, for example Toshiba. I'm mainly concerned with picture quality (naturally) and tweakability. If you can offer any advice I'd appreciate it.
