I think the vast majority of people now have a DSLR floating around somewhere. I for one when I got my scope spent an extra $30 on the adapters rather than spending a lot of extra money on a dedicated Asto Imaging camera.
The DSLR also allows you to tek photos of things when your not looking through the 'scope.
Personally, I think they make a better introduction to astronomical imaging. so long as you already have the camera that is
