I've owned both the 60D and 7D and I would recommend the 7D without a doubt, the improvement over a 60D is massive. If I had my time again I would have just bought the 7D in the first place, although compact flash cards are more expensive they are also better if you are thinking of upgrading to 'more professional' cameras. Also the fps on the 7D is absolutely amazing.
I could not recommend the 7D more.
