I'm quite happy with my first projector, an Epson Powerlite 8350 which I purchased last spring. 509 hours on the lamp and still going strong. I guess I should clarify that I am happy with the replacement. At the time of my purchase, the reviews made this one seem to be the one to get, although some complained of "auto-iris errors". Sure enough, mine started having them shortly after purchase. After a few annoying months of worrying about "is it going to come on right this time?", I called Epson support who said "oh yeah, we know all about that issue, send it in for replacement." The replacement had a completely different serial number scheme, so I can only believe that Epson knew about the problem from the beginning and decided to "get them out the door, we'll fix them later". The replacement has only given me one auto-iris error (and that's with auto-iris set to "off" in the menu"). I actually find the whole "auto-iris" concept annoying. When it is turned on, if you have something along the lines of just a white mouse pointer on a black screen, the auto-iris dims the picture so that you can hardly see the pointer. This was causing some problems viewing things like "World Wide Telescope", so I turned it off. Everything looks great without it.
It projects on to a 109" screen. The screen is just white primer on non-textured drywall. The sorrounding area has "orange peel" texture and an earth-tone paint color. The picture is beautiful and if you get close enough, you can clearly see each pixel. Computer screen and sports show up clearly with a significant amount of ambient light and darker programming, such as movies, really shine with all of the lights off.
I expect to keep this projector until 3-D LED projectors become mainstream. If there are better models out there, that would be amazing to see, because I find no fault with this one's picture. I run it with most settings to factory default.
