I have never seen the 7210, but it has higher quality components such as the DC3 chip, DCDi deinterlacer and scaler, and high quality optics. It's original price was somewhere between 3k and 5k. I have the Hc1500 (Hd1000u actually) and it is a good projector, but it does have its downfalls such as SD material is average and blacks aren't all that black. I actually get headaches watching the Mitsubishi sometimes. I don't know if it's the color wheel or not. I can't comment if the 7210 has a better color wheel or not. I think most video purists will say that the 7210 is a better machine than the Mits.
I am actually considering switching to the 7210 since the price seems to be very good on it right now.
