This is a fantastic deal ( 78% off most current MSRP, 91% off original MSRP ) on a great projector, if you get a good one. Very enthusiastic review by Art at projectorreviews.com:Samsung SP-H710AE review
He states that the detail in shadow areas is outstanding, that it's the best calibrated projector out-of-the-box that he's seen shy of the $18k mark, and it does a beautiful job with movies provided you keep the screen size below 110" (preferably at or below 100"), have a dark room and preferably dark walls. He doesn't recommend this projector for lots of sports and HDTV viewing, though, as it isn't bright enough to handle much ambient light. I'd snap one up right now but for the fact that I need something brighter for a lower level rec/HT room with lots of windows.
One other caveat: this Samsung is around 19lbs making it twice the weight of the typical HT projector - I don't know if this added weight will make a difference as far as ceiling mount selection is concerned.
Thanks for the heads-up on this deal (forum rules be damned).
