The samsung actually has a 6-segment color wheel. The Mitsubishi has a 7-segment wheel. I have seen the Mitsubishi DLP first hand and it is a very nice set. It uses TI's latest HD2+ chipset and is one of the first models that does. It includes an ATSC tuner as well as HDMI and 3 firewire inputs.

I am actually looking at TVs as well and it is on my list to consider.
