John,
Here is the official thread on the QHY forums discussing the CMOS guide camera.

One of the members has posted some of his pictures taken with the camera here.

Also check out the SAC4-2 and the Orion Starshoot for similar chip camera's. You can then see what images have been taken with them to compare with.
As a Gudie camera I think its quiet good as it has built in ST4 guider. I assume this means that you can plug this direct into your autogudier ports that support st4, with no need for an external software like guidedog etc.
Regards
