Panasonic AE-500 Projector, on a 118"x80" (approx) screen, and it's no short of amazing, the only issue which I faced was that the DVD is 4:3 and on a screen this size it really doesnt go well, but I managed to use the Projector Zoom function which worked wonders, and spread the image against the whole screen. The DVD player used was a Philips DV642.
I simply cannot wait to see the other ones.
