I'm in the market for a projector. Considering the Optoma HD20 Full HD projector. My room is pretty big and capable of projecting an image between 130'-150'. A projector screen that size will cost in excess of 5K. Anyone know of alternative's that'll give me the image quality equivalent to that of a 1x gain screen? From what i have read on the net a few guys have used materials such as Melamine and Blackout cloth seems quite popular....
