Hi folks. I'm putting together my first home theater, and I'm wondering what kind of screen I should get. Here's the details of my setup: - 12' x 25' foot room, flat dark paint, no light - Epson PowerLite Home Cinema 3020e, ceiling mounted, 14' from screen I plan to watch 3D content (active) fairly regularly, and I would prefer a pull-down screen as opposed to a fixed one. I'm thinking I want a 130"-135" 16:9 screen. I'm hoping I can find something in the $400-600...
