I have kind of a sad story, actually; my 3000 series (so, really early) fat PS2 was working until about two weeks ago, when I dropped it from a height of about two feet and screwed up the disc tray. There are a couple of repair shops near where I live, and I'm seriously considering getting it repaired. It needed a laser adjustment anyway.
In the meantime, though, I've got a slim PS2 that does work; my parents bought it as a cheap DVD player, and since they now have a nice upconverting DVD player, they let me have the slim PS2 to take to college with me.
