Picked one of these up a couple weeks ago at this price in Reading, PA hoping that maybe the Vita would use the same charger input... not even close. Oh well, for $1, it wasn't the hugest risk I've ever taken. Kinda silly to have without a PSP, though.
Very ymmv as I picked one up 2 months ago. Doubt there's much left out there. Best buy clearanced out most of their psp accessories to make room for vita awhile ago
