I think it depends on how much of a 'beginner' you are.

If you know your way around shutter speeds, F-stops, and such, just about any D-SLR is going to keep you happy for quite awhile. If you're moving up from a point-and-shoot, you might be overwhelmed by that much camera. ::shrug:: I guess it's just personal preference and how deep into photography you plan to get.
Me, I'm dumb--I knew I was really getting into photography, but I still worked my way up the ladder of point-and-shoot to high end consumer camera to prosumer DSLR and now I'm wishing I would have waited and just gotten a good true DSLR. But live and learn, I s'pose!
