As Greg said, but wanted to emphasise-CHEAP!!
Get an old 450D or 1000D off ebay and you can modify it and even add a cooler.
Saying that -it seems most people gradually migrate to specialist CCD's from DSLR's once they have messed about with DSLR's for a while.
I like my DSLR but I anticipate when I get to the stage of having an obs and a G11 etc, I will probably also have an SBIG etc to go with it.
Pipe dreams at the moment though.
