Excellent projector... when working. At 500 hours I had the infamous "IRIS" problem. After 2-3 min the projector would shut down. It is now at Heartland in Kansas for warranty repair. Despite this inconvenience, for the price, the performance is superb.Like: high light output (can watch during day, windows open using "DYNAMIC" mode), superb picture on 120" screen - almost looks like 1080p to my eyes, flexible placement options with lens shift & lots of zoom, nice remote, quiet, accepts 1080p signal (but displays at 720p), also accepts 1080/24 signal from PS3 for smooth film-like playback.Dislike: reliability (Iris issue), air filter not too easy to access when projector is ceiling mounted (minor issue)
