Well... this is for your benefit... not mine. (I already have my PS2) But feel free to thank me with a PS2 game or cash. (just kidding.... kind of... =)... )
Anyway... if you're in the LA area... I have heard that Game Headquarters (GHQ) in Alhambra, California has more shipments of the PS2 coming in on Monday than they have pre-orders for. It is pricey because they put it in a bundle, but may be well worth it. I'm sure it's worth checking out.
They are on Main, just east of Garfield. 626-588-1600.
It's $500 for the bundle; they have three different bundles.
Last I talked to them was yesterday, and they plenty. So, if you got that kinda cash, go get em!
