Digital Projectors - Under $3,000 USD MSRP
I use my Epson Home Cinema 8350 ass my main tv, both daytime and nightime. Its pushing 5 years and about 4,000 hours. First bulb died at 1300 hours, current bulb at 2700, and 3 years old.
I run 120" screen fed by a directtv hd dvr and a roku. Some ambient light in the daytime.
