2nd body for studio work?

I currently have a 5dc and while I love using this camera, one of the downfalls I have found is that when using it for studio setups it doesn't do tethering to my PC. I really would like to be able to do that as well as live view.

So I figure I would look into a 2nd body for when I do studio work. Unfortunately my current budget is in the $600 or so range. I would like to know what body would be a good choice ranging from the T3i to the 60d.

Any and all suggestions & comments are welcome.

For that budget, sounds like a 60D to me.

+1. 60D's are crazy cheap relative to their quality right now. With that budget you couldn't go wrong with one. I think you'd be let down going to a Rebel from a 5D, with respect to their controls. The image quality is there on the Rebels but the controls are decidedly better on the 60D.
