Hey, I do alot of work with cannons, I love my 5d and my L glass. Now if I was in your position I would probably go with the cheaper of the 2 bodies and save the extra few hundred to invest in a really nice lens like a L 70-200 that would probably work out pretty awesome for your daughters meets. But then if you are really going to be using it alot you might want to go with the one that feels best, the 60D. Avoid the 7 they are great but if your going to spend that much money put out extra cash and get a full frame 5, and it just seems like that deal is a little sketchy... to say the least. Like others have said the 60D would be a great option in terms of FPS and the focus speed, but the rebel will probably meet all your needs.
