Good point Doug. I was thinking of a modded DSLR with cooling. Even with cooling, there will be greater heat on a DSLR chip than CCD Astro because of the larger chip...

Most modern DSLR's are capable of 5 minute exposures with ease but do require darks to be taken. You will need to take a good number of exposures and stack them to get the best result.
As to which camera? I would go for the new DSLR. It has a much bigger CCD/CMOS and is very capable of producing great images.
