I don't know much about the 60D, in specific, but generally speaking I'd encourage you to get a new camera rather than an older one. Time marches on, and sensors just keep getting better.

Since you're starting from scratch, you should give some serious consideration to your alternatives, including the various Micro 4/3 cameras, the new Sony NEX cameras, etc. For standard D-SLRs, as always, it's between Nikon and Canon. Both are quite good.
