im too lazy to read thru the post. i dont know what your price range is, but im pretty sure last time i was at HHGregg, they had the new mitsubishi 83" rear projection LCD w/ DLP. ive seen your living room, and i dont think you'll like a 65". i bought the 60" last year (wd-60735), and in my 1/2 basement/family room, its probably 22-24' long, 14' wide, and i have the viewing across the long end, and the TV almost looks small.
im waiting for my buddy to sell his 73" model of the same tv so i can put it in my basement and have a better viewing.
as for the picture, im happy with it, and blu-rays look good
