Tony,
From what I have read here and on CN the chips are in the same category as the SBIG's. You can get BW chips as well. He has just posted about a QHY11 using a 10MP CCD

Check out the images being taken with these cameras.

SBIG Cameras are overpriced. If one compares the cost of the CCD sensor vs the cost of the manufactured unit there is a very very large gap.
