I bought a broken PS2 off of eBay for $46. The seller said it had a "Disc Read Error" problem. I took it apart to see if I could fix it myself (adjusting the gear and all) but I couldn't, so I called Sony and shipped it to them. Free repair. Sweet! I'm so excited.

Shipping it to Sony was only $12, so I just got a PS2 for 58 bucks! Ha! Can't beat that. :)
