I recently put up my Ps2 and I've got the same offers. Those god damn Africans think I'm stupid or something, but I'm not dumb enough to get screwed out of a ton of money. I told them about how I saw one of them get caught on an ABC special or something, and that guy started crying like a little b*tch. I didn't get a reply back.
BTW, if anybody is interested:
120gb hard drive
Hd loader disc
about 10 of the newest games(Madden, fight night, and many more)
All for $225
Can hold up to 50 games on the hard drive, and its very simple and in no way damages the PS2.
