i heard of ways you can fix your psp screen for little to nothing!
source 1)i DROPS:these little babies are made of the same material sps screens are made of! in liquid form!put droplets on the screen and spread it around it fills in the scratches!(clean the screen before applying)WHERE TO BUY THEM:im not sure but you can get them on amazon.com! PRICE:$3.99 plus s+h
source 2)repair man:go to eb games or where ever you buy your games and ask the guy at the counter for the fix!(some game places dont do it but they will direct you to where you can fix a screen!)it will cost about $30.00 but well worth it! they will call you when the screen is ready (it takes about two days for them to finish)
