I have the HD72, bought it last week from ProjectorPoint. It came with the $300 rebate, and a free replacement bulb, shipped free. As of this week, they still had a few bulbs left, so that might help you in you decision.
I posted some pics of it in action at:

So far I'm loving it. It has great contrast, nice blacks and bright colors, plus 2 digital inputs which is nice. I'm sure they could be tweaked like Michael said, but out of the box I'm very satisfied. Hope that helps!
