I almost got that, but by the time I was goign to check out it had sold out. : lDell was selling them for about $110 new (2000s) not too long ago. I'd say keep watching Slickdeals ... another one will pop up eventually. I'm guessing the release of the Go will lead to some retailers discounting their 20000s/3000s.
Gamestop has used PSP-1000s for $100.
What extras?I'll sell you mine, mint condition with a 4 gig card and extras for $150
