Summary: Personal Experience I purchased the Sony for $800 from an on-line vendor. I have it ceiling mounted about 15 feet from a custom built screen (approx 120" diag). I'm not a videophile, but for me and my guests, the picture is amazing. The unit is quiet enough that it's not noticeable. At such a large screen size, there is minor "screen door" effect but only if you are less than 6 feet from the screen (way too close).
Summary: This projector is perfect. I was willing to spend 5k on a projector, and they talked me in to this unit and I am very happy.
Pros: Very nice projector for the money. This installation was easy as well. Installed in a 72' long x 54' wide building about 18' from a 144" screen. The projector is mounted at about 13' from the floor. Everyone who sees the picture cannot beleive the HD quality of movies and such. we have had masny parties and many critics and they all love it.
Summary: When we built our deck, we wanted it to become like a room addition, a place where our family would spend time together, and where we could entertain friends. We don't have a pool, so we decided to have backyard movie nights, and began looking for a projector. Since our "screen" is a tan stucco wall, and light levels vary greatly, we did not feel that a 1080 native resolution unit was worth the extra cost.
Summary: I just bought this and find the color and brightness very good. I have not compared it to another projector, and I thought I would regret not getting a 1080p projector, but last night we watched 7 Years in Tibet and it was spectacular. Limited zoom and a bit loud if you like to keep the volume low on your system. Focus is very smooth.
