I also bought a 7d about a month ago, was debating about getting a 60d, but my dad convinced me to go up one, basically cos i want to have it for a long time and the build quality is amazing, waterproofing definately helps.
I do miss not having a flipy screen, but so far i cant really think of a time when i really needed it... as far as performance goes, they are the same, other than focusing, shutter speed and the manual audio adjustments... So far I've spent just over 1.5 k, having said that, mine was a refurbished model so was alot cheaper...
Like everyone says, definitely try before u buy! I would definitely recommend the 7d!
