Our sister-site, Engadget, has done some fine work and posted a list of the best/only PSP deals out there. This is a tough job, considering the units have all sold out, and the vendors are mostly hobbyist shops. The eBay angle is really iffy, so please be careful. We'd suggest you only buy from an eBay member who has 100% feedback from at least 100 people, and has sold within the last month. That's strict, sure; but losing 500 bucks to fraud could kind of suck.
