Hi, I'm a new here. Yesterday I traded in my ver.4 PS2 for a used one at EB cuz of a laser problem. I got a question, how do I know I got a good machine?? Is there a way to check if I got a good one or does time tell?? I don't mine opening it and see cuz I opened up my old ver.4 before and I had no problem doing it. Wanna make sure I got a good PS2 before I start modding it and put a HD. btw, which site was it that tells you what version your PS2 is?? I forgot which site it was, the PS2 I have right now is SCPH-50001, I know that it's not ver. 1-3 cuz it has 8 screws, thanks a lot.
