Well, I bought a used PSP, but there are some scratches on the "screen." I want to buy a replacement, but I'm not sure what I need to order. Looking at the machine, there or no noticeable gaps between the 'screen' and the faceplate where the buttons reside. So if I order a new screen, will I still have scratches, because they are actually on the outside faceplate? Also, can I get a PSP sized phillips head screwdriver out commonly, or should I plan on ordering one of those too?
