Sony A57 SLT vs Sony CX760v/PJ760v camcorder for video?

The sony is a good product, and so is the canon G10. I don't mean to throw a monkey wrench into the mix, but one of the reasons I settled on my Panasonic x900m was that it had almost identcal specs as the other two, but at hundreds $ less. The pany is known to be the sharpest of the 3, IS is very good, just a hair behind the sony, and it has audio jacks for mic and headphones. The canon is $1039, the sony is $1250, the Panasonic is $740. Just a thought, I think anybody with one of these will love it, but if a budget is a factor, that would save you $500 over the sony.
