You can do a widescreen setup with many projectors without having to get a lens. They have memories on the zoom and shift lens settings - just zoom out for widescreen and let the black bars spill off the top and bottom of the screen. Epson, JVC, Panasonic and probably others do it. You'll need to black out the screen wall to absorb the left over light though. Works great!
