If you have a Microcenter nearby they have screens. Check out this thread http://www.avsforum.com/t/1488332/help-deciding-on-cheap-screen#post_23705138. Microcenter has these 100" grey screen with a 2.8 gain they are practically giving away. I picked up mine for $40 and some stores across the country have them for only $25. I haven't set it up so I can't review it, but I would never pass it up.
