I am looking to buy another 21". I may get another Mitsubishi since I have been very happy with their diamond pros in the past but I may get a Sony too(I own both Sony and Mitsubishi currently and like both). The Sony model I am looking at is the 520. But the have both a CPD-520 and a CPD-520P. And I can't really see the difference between the 520 and 520P. They look like they have different cases but is that it? On Sony's sight the specs look the same. And the cost is about the same. Anyone know why these are so similiar? Is one replacing the other? I considered that but I would think if that was the case they would not both be on Sony's site listed at the same price. Anyways, any insight into whats different between the 520 and 520P would be appreciated.
