TS, you should think through what is limiting you on the 60D.
Nowadays, everyone seems to need that 24-30fps frame rate; thats called video btw and its avaliable on the 60D too
60D and 7D share the same sensor. You pay more for the fps and slightly faster AF, you have to decide if the money spent is worth it to the photos you do.
Frankly, with only 3 months under your belt with the camera, I think its more worthwhile to learn your camera/lenses and technique properly.
Ever seen some of the street/candid shots done in that sub-forum with an iphone? Puts many DSLRs users to shame.
Its always easy to fall for the instant gratification and fallacy that better camera means better photos.
Its so easy, since its just the press of the PIN and swipe of the ATM card, while technique needs to be learned and sometimes not even.
At the end of the day, its your money, and who am I to tell you not to spend it.
There will always be those who will give you 'air wear' remarks like "Once you try XX you won't look back" "XX sure worth it over CCC" ;
But ask the hows, whys?
Where is the proof in photos?
