Hey Drew,
Sorry for the late reply.
I ended up buying the 60D and am very happy with it.
My friend owns a 600D and they're both pretty similar,
It depends on what you want to do with it.
But the 60D feels a little more robust, has a bigger display, bigger body, more knobs and levers and a longer battery life.
This is a comparison of the two:
The 60D's generally better, so if you have the money, I'd recommend buying it.
But if you're just shooting video and are on a low budget, I'd get the 600D and use the extra money to get a better lens.
Just my 5 cents, I'm sure others would have better advice.
Good Luck :D
