I might be directing you to the enemy here, but you may want to post that question on avsforum.com. They have a decent little board that's all about projectors and the like.

I've been doing my own little research into projectors since I've seen their prices drop under the 2 grand range. I really love the screen size, of course, plus the overall portability as I currently live in a rented apartment. The major differences I've seen between the technologies has been the "screen door effect" with LCD, the "rainbow effect" with DLP, and the "Oh my God that's expensive" effect with CRT. Basically, it comes down to what trade off you wanna make with the current technology and your price range. IMHO, once you reach about 4 grand in price, it's more worthwile to be looking for a plasma screen.

If you do find any good tidbits about the newer DLP projectors, please do post.
