just got my power book 15in and put my 2 1 gig sticks in it, so i now have no need for the 512meg stick that it came with.. dont know how much it is worth, so make an offer.. just looking to recoupe some of the cost of the 2 gigs of ram.. dont know how much to ask, but mabe more than 50$?... in any case just make an offer.. its just taking up room around here.
