depends.
Do you want video?
Do you need a very tough body (the 60D is good, but the 7D is better)?
Do you need super fast and customizable AF?
Do you need fast continuous shooting?
Would you benefit from a swivel screen?
Unless you need fast shooting and fast AF, the 60D should really do everything you need, but cheaper and lighter than the 7D.
Honestly, unless you need speed, the extra money of the 7D would probably be a bit wasted.
For most people, a camera like the 60D is as high as you really need to go with crop sensors, and the next logical step is up to a full frame.
