no no no, not the psx, this is a hard drive that goes in the expansion bay of the ps2. It runs around $80(expected) and will be availible around x-mas. It comes with the music/video software too.
I was refering to AximDave's post, the one above mine, which is why I did not use any quotes. Also, the PS2 HDD will be out in early to mid January, and should run for about $100. I will be getting mine for free though, as I was a FFXI Beta Tester.
