7D (Very nice, but do I want to spend the extra over the 60D)
Yes, yes, yes----Though I have not used the 60D, I was the proud owner of the 50D.......and the improvement in my photos jumped a great deal when I purchased teh 7D. I know the general idea is to get good glass first, but I think in your case, the 7D would be would be a good investment. I am probably the outsider on recommendations for you, but the 7D really did make a huge difference for me. It was probably the single best upgrade that I have made.
