[SticK v2]

I bought it the other day, and it is a pretty good accessory for every PSP owner. What hurts it though it the fact that it looks like a fat block attached to the back of your PSP. I would probably reccommend buying two 2GB memory sticks instead of this. But it does come with a battery that supports two times the battery life of the normal battery, and it has some useful media manager software.
