I have a 65" Mitsu DLP that I bought a few years ago (quite a bit more expensive back then). The picture is great. I think the main reason DLP's fell out of favor is that you can't hang them on a wall and they are more then 2 inches deep. I have an LCD, Plasma, LED and a DLP projector in my house and the DLP tv does not suffer in comparison (the LED definitely has the best picture but it's the latest and greatest techology, it should).
The DLP technology does have one advantage over LCDs in that it presents black much better (LCD blacks look more like a really, really dark gray). Its a goofy videophile thing. In projectors, DLP's are much preferred to LCDs.
