Ok. I just bought my second house and this one has a basement. Talked my wife into letting me build a home theater. I'm in the middle of building it, have my walls up but just open studs for now. The room is 12x20 with main seating about 11 feet away and second tier 12" up about 16 and a half away. The projector I have picked out, not bought yet, is the epson 8700ub. But the thing I'm stuck on now is what screen to get? First I don't know on the size I should get, next have no clue what brand or anything else?
