I have the G1325V carbon legs (the older version of what he's selling) and love them. I would recommend against the 501 head. I've used it a lot and found it lacking in smoothness of tilt and pan. Too much sticktion. I've heard good things about the 503 but haven't used it.

Run and buy the guy's tripod before it's too late!
