I've had a 3010 for about a year and a half. Using it with 120 screen, grey, 0.8 gain. It is in my living room with all white walls and I only watch it at night. Pretty happy with projector except for the iris.
The iris is pretty loud, maybe it's normal but it bothers me. Was going to upgrade to 5010 (the refurbished one for $1800) but afraid will have same issue with iris. Don't play games, mostly movies and sports. A bit of 3d. Projector is 2-3 feet above the sitting position, on a wall shelf, about 12.5 ft from screen.
Is 5010 my best choice or maybe sharp or hc5? 2d picture is top choice along with being quiet.
I may also upgrade my pulldown screen to dalite hp 2.4 is I read it does not show waves/wrinkles as much as my current one does.
