Love the big screen and big sound. Before the below, I had an Optoma HD66 (1280 x 720) DLP Projector with the same sound system and screen. I also have a 120" screen that I occasionally use, though I haven't for many months now, maybe over a year.
Projector: BenQ MW523 WXGA (1280 x 800) DLP Projector - 3000 ANSI lumens.
Screen: 92" Panoview Graywolf II Home Theater Projector Screen.
