I picked one up today at my Babbages in Portland, OR if anyone is wondering. But it was the last one, I had to have them hold it for me. However, the gamestop, ebgames, and gamecrazy all said they should be receiving some in soon.
It works well as a protective case, but I must say its much larger than I imagined, I feel as if I could kill someone with it when my PSP is inside.
