I have an early version of PS2 and my son dropped it a few inches. Since then the little shelf that holds the game disc won't work. I thought about opening it up and taking a look - always my first impulse - but I can't even see how to do that. Is this thing toast? I really don't want to buy another. I would like to get a PS3 but living in the midwest I don't think this is going to happen any time soon. Can anyone give me some idea on how to open this sucker up and tell me what to look for? thanx in advance.
