Okay, so I have a black PSP 3000 and a white PSP 2000. There are a few things I want to work on. First, Neither of them have battery covers, and I'm using electrical tape. Where can I get the doors and a battery for cheap? Also, the screen on my 3000 is broken. Could I replace it with the 2000 screen, or should I just buy another one, and how cheap do they go? Thanks!
