I currently own a Panasonic AE900 (my first projector) w/ a 92" 16:9 screen. The PQ is great (HD-A1/XB360/PS3 etc), I'm really enjoying it but I'm considering a larger screen. How big does the AE900 go? How big can I go before the PQ starts to degrade? Any thoughts/comments/advice would be greatly appreciated.

Well, the 900u has a 2.0 zoom factor, so it is mainly going to boil down to distance to screen and seating distance. Use this 900u throw Calculator (http://www.projectorcentral.com/Panasonic_Home-PT-AE900U.htm) to see what is available, but at 15', you can have a 149" diagonal screen at max zoom. Far from optimal, but a possibilty. I'd say you could easily have a 120" screen with no issues at 15'.
