I paid $1045 for my Sanyo PLV-Z5 from ProjectorPeople last year. Throw in another $35 or so for materials & paint for screen and I have a 92" screen for much much less than a TV would have cost me.
Looks like they're OOS at the moment though.
Oh and do your research, and a lot of it. I spent probably a good 3-4 weeks researching before I decided on the Z5. Everyone's room, personal preferences, budget, etc are different.
