i beleive thats 109" screen i can't remember.
I love the projector, its awesome due to the size and out of the way location.
Mounted it up on the ceiling, all the cables routed through the wall, and the screen mounted on the wall. It is preferable to get a screen if you are picky on the picture quality, but if you aren't go ahead and just sand the wall smooth and paint it with a eggshell paint, you could paint the whole wall or you could just paint a border. There is a specific paint color i can do some more research if you need, but projectorcentral.com is a great source.
Personaly what i have is a Panasonic PT-AX100U, total i spent on all the cabling, screen and projector shipped was right around $3400. I already have about 600 hours on the lamp, and don't regret it at all, i can make the room pitch black during the day if i need to but generaly i don't need to at all.
The picture taken was with all the lights lit up in the room and flash, yet you can still see picture a bit and thats in economy mode.
I actualy might be actually getting a 60" plasma for free from work, so i might be looking at geting rid of the projector.
