Probably a bit late now, But Epson is by far the best contendor. Can vouch for the Ultra Short Throw ones especially in use with a SmartBoard. Reduces shadows so much. If you connect them to a network then remote administration is also avaliable. I have found Casio and NEC to be super painful, issues with lamps, image fading, focus just to name a few. Epson's UST mounts are a lifesaver with installations, and quick corner as well as their low priced lamps make it a no-brainer for me.
