I have 2 bigger PS2's that work fine. One from release that has not needed service yet and another that I got off of a friend because the drive wouldn't close (which works fine now). I travel a lot with my PS2 so I was thinking of getting a slim PS2. One of my friends is willing to sell me his for about $35. The only catch is that it doesn't read any discs. Are these DRE's in the slim PS2 easy to fix? Do you think I should go ahead and buy this PS2?
