I've noticed a few of these "Send us your old PSP and get a new (or recon'd) slim one sent in replacement" auctions on ebay when searching for PSP related stuff. The prices seem to range from around £15 to £30 and the sellers have positive feedback for these 'services'.
I'm wondering what the deal is here, and how they're doing it?
Edit: I see there are similar ads for PS3 swaps too, off the top of my head I'd guess that you pay say £20 for the pickup, the guy sends you a refub'd unit and then sends your one off to Sony for repair to sell on after it gets back with a new warranty?? Dunno how much money would be involved in doing this though! I'm curious.
