alright, my PSP's battery is nearing its end, and a damn good job it's done....but I'd like to get a brand new one in the next week or so, since I'm going on vacation next month and I'll need my PSP for the long ride there...

I was looking on eBay (GASP!!!) and found this one... CLICK HERE

while a battery like that for THAT price would be nice, I'm a bit suspicious....after all, the price seems TOO low, and the extremely generic packaging really concerns me....plus, this IS eBay, and wee all know to be wary of certain PSP-related things on eBay, particularly memory sticks from Hong Kong and such....

any suggestions?
