Ditto.

The laser motor's gone, mate. If you want, open it up, set the laser in a position (I'd say right back), turn the console on, stick in a game, leave it a few minutes, then stop it, and look at the laser - I'd bet your house on the fact that it hasn't moved.

You can send it back to Sony... or you can find a PS2 that's broken, but with a good laser that works, and chop the two to bits and build a working PS2. At least, that's what my Dad did.
