Why do you have a projector vs a regular tv? Are they better quality? More expensive or less expensive? I personally would want a regular tv.
My main TV is a projector setup (Infocus IN76 720P). Obviously, you cannot touch the size with any other technology. When I bought my projector about three years ago, I paid about $2300 for it, and another $700 or so for the screen.
At that time, it was hard to by a 50" HD set for under $2000, and most mid range (not high end) 55"-60" HD RPTV's were $3,000 plus.
I paid $3,000 for a 118" HD setup. Granted, I have to replace the bulb more often then an RPTV, but if I had gone with a decent 60"+ set at that time, it would have cost well more than I paid, and be tiny in comparison.
