Looking for Projector for gaming, movies, and TV.

This is a new thread from a newbie so bear with me and...be gentle. I have a 24 by 20 square foot soon to be HT room. 480 square feet. I have 7.1 surround sound and am looking for a multipurpose ceiling mount (about 13 feet from the wall) projector that can handle and perform well for xbox, TV, and DVD movies. Is there one out there that anyone recommends that can do all those things. I would like it to be somewhere in the neighborhood of 1000-1500 dollars if possible. It doesn't have to be the newest and the best (obvious from the dollar amount) but one that will do the job. I have good lighting control with only two windows and dimmer lights. Any help would be great. I have been looking at the optoma 1690 or the mitsibishi (SP??) 1000?? Anyways, thank you.

Thank you for your reply's, I guess I worry about not getting enough lumens or contrast ratio. I am looking for bang for my buck, and I think the mits 1000 is looking pretty good right now. Thanks againl.

Ceiling is 8.5 to 9 feet. I don't even know what this offest thing is your talking about?? Please fill me in. Thanks
