I have a 56" JVC Projection TV I bought about 5 years ago. It is still going strong, like brand new. It does 720p and 1080i, no 1080p.
I also moved recently (November) and built a Theater in my new house. It is a 10' x 24' room with a 12' high ceiling and no windows. I mounted the projector to the ceiling and you can be within about 5 feet of the 8' wide screen before the shadow of your head cuts into the picture. But there is 12' between the screen and the front row seats, so lots of room to jump around playing my Wii.
