I bought two different cases off of eBay and one from Target, and none were very good.

One is a metal case that looked good but really sucked in practice. One of the biggest problems was that it wouldn't stay shut. the clasp was just a lip pressing against a small nub. It popped open at the slightest touch no matter how hard I tried to bend it to be tighter. It also didn't protect the cover and was in general just crap.

The second case claimed to mimic the Logiteck Playgear Pocket. It didn't. It wasn't double hinged so it wouldn't open up to act as a stand. The interior black rubber was thin and very hard, unlike the Logitech, and put a few wear marks on the psp face. The hinge also had two small pins that held it together and they kept sliding out. I finally lost one and now the case is useless. It was the best option until Logitech comes out with one.

The third I bought from Target after the second broke. Utter garbage. Target should be ashamed for selling such junk. I couldn't find a link on their site but it was called a bumper guard. Basically a crap plastic edge with a hard plastic face plate cover that attaches (if you can make it work - I couldn't) using plastic screws. Ughh.

I'm still searching for a good case. I might have to settle for one of those enormous travel cases until a true game case arrives.

But be real careful with the eBay and Amazon cases. They can look like something and promise plenty but I found cheap, thin, brittle plastic with hard scratching rubber and poor at best protection.
