I got a broken Psp2000 for pretty cheap. I replaced the shell, analog module + jelly bar, and the mem stick with an adapter. I tried to reuse all the original parts I could, but a lot were missing/shattered. I lubricated the umd drive, and cleaned the screen up as best I could, but both still give me intermittent issues.(blotchy water-like damage looks like alcohol seeped inside or straight up water damage) (when playing umds I get rapid fire "do you want to close the game" pauses, home button definitely not stuck or anything like that) (the cheap $18 shell is, well cheap, thin plastic sloppy holes)so not perfect.
This thing is the best! I immediately updated to 6.61, and started enjoying all my games. I put some xxx movies on there, I got mp3's. Every psp game I can imagine I'll ever play, and still 50gb left. Can't believe how well it runs, and how crisp the display is. It blows the DS away (my closest reference). Happy to be on the team. Let's enjoy these while we can!
