There is a pretty big price gap between the VX2000 and the Panasonic AG-DVC7. I was wondering if there is a big preformence gap too with these two cameras?

Despite the AG-DVC7's design to look like a "professional" ENG-style camera, it's a 1-CCD (1/4") camera that really is not in the same league with the 3-(1/3")CCD cameras such as the VX2000, PD150, et.al.
