DSLR vs. CCD for DSOs

I'm getting kind of bored chasing after Saturn every night, so I'm considering branching out into DSOs. Had a great night last night! I spotted M27, M57, M81 and M82! I was stoked!

Anyway, I'm considering the purchase of a Canon 40D (don't want to wait for the 450D). I've read that exposure time can go beyond 30 seconds if it's taken to manual mode. Does anyone have any experience with the 40D? All reviews max out the exposure time at 30 seconds. I don't want to have to modify the camera for longer exposures.

Also, I've been looking at an Imaging Source CCD camera. I notice that max. exposure time is 60 minutes. Can you successfully do long exposure imaging of DSOs with a CCD camera? I can't find any image samples on the web.

Any help would be very much appreciated.
