Looks like I'm getting the Epson 8700 projector for a completely dark (no windows) 12' x 18' room. Looking at a 92" screen (or slightly larger, at most) from Screen Innovations. Will a "basic" Sensations series screen in matte white do the trick (running about $500), or should I invest more money and look at something in the Performance or Reference series? Don't want to overspend for something not necessary, but want to make sure I'm serving myself well. Thanks!
