I've read, read, and read some more. Everytime I think I have decided, I read something else that makes me change my mind.
Variables: 13x18 Room (8ft ceiling), almost total control of light, so virtually pitch black if I want it to be.
Projector: Epson 3020
Size-big as I can get. But looking around 120-140ish size
Color--I'll paint the walls/ceiling whatever is necessary. I'm initially looking at a "home theater red" for the walls and black ceiling.
