I'm not the only one , thats crazy here.
You would think that most of them on ebay are probably older versions. If you wanted to buy a ps2, I would check the guys here and get a trusted site to buy from. Cost might be slightly more up front but in the long run, you just might save a buck or 2.
To coin a phrase, Ebay is like a Box of Chocolates, you never know what your gonna get.
