I have been looking for the rp82 with no luck. I've heard that the cp72 is the same as the rp82 minus the fact that it changes discs where the rp82 doesn't. Are there any other differences? (Particularly in picture quality) or are these 2 identical for the most part except that for the changer? If so i may just get this as i don't see a reason to wait up for the rp82.
