You can get the Logitech fussion, which is a CMOS camera showing lot of promise, but it requires major modification for telescope use.

I have discussed this with Steve Mog and he has suggested he could make a telescope adapter to fit directly to a hole in a Radio shack case.
I am waiting to see the Planet imaging results from the QHY Guide camera. Before I make a decision.
The Fusion can be picked up from ebay for ~90 bucks or less if your lucky.
Andrew D, thats a very generous offer, I to have loaned the Neximage from a mate. Middy I would take him up to get started to see what else you might need.
