I am looking to buy a second hand PSP and I've mostly decided on what I want to do, but I want to know if there are any negative results. I think I will be going with the 2000 because it's apparently harder to accidentally brick, I don't mind the screen and they're a little bit cheaper. Is there any difference between the PSP 2000 and the PSP S&L or is it just the name? I know with the 3000 the 9g is to be avoided, are there any models I should avoid with the 2000? I don't understand what the difference is between 6.20PRO and 6.60PRO. Will any games be unavailable depending on whether I choose? I am looking for a permanent install. But how permanent is permanent? Does it just mean that it will boot automatically or does it mean I can't change it later? I may have the opportunity to get a PSPGO but I haven't read much about hacking for it. I am interested in playing with a PS3 controller and using my tv for it. The lack of a UMD drive doesn't bother me, but the reduced battery life does. The model is PSPN1002, that's all the information I have so far. Is there anything important I should know about modding a PSPGO?
