Great, affordable 720p pj...suggestion?

My old faithful infocus 4805 is having some issues after about 2000hrs over the last couple of years. I know this is not much hrs/time but I have this dark/shadow like area on the right side of screen that takes up approx 8 inches of the screen side. Not too distracting in most scenes but you know what...it's a dinosaur and it has to go. So...what's the skinny on a great/cost effective 720p projector and from what dealer preferably online to save most? Thanks.
