soo i have 2 ps2 1 of them is the original fat one and the other is the newer small one.

im thinking of trading in the fatter one.
anyone ever traded it in at gamestop or ebgames or even gamecrazy i guess
you did how much did you get for it?

it turns on and everything but i think the lens just needs to be cleased really good becasue it sometimes has problems reading the disc
it just says "can not read disc " or somethin.

Why not try calling your local GameStop or Game Crazy to ask? I doubt anyone on here will know the exact prices, and it varies.
you COULD try selling it on ebay... there might be a few buyers. Just set the starting bid at the price that you would get at gamestop.
