Where can I buy a protective cover for my PSP 1001?

I've been to Best Buy and GameStop and they only have skin grips for the 2000 and 3000. I really want one of those grips that you slide on but I have the fat 1001. I would have tried a faceplate (not sure if those are for the slim or not) but they only have retarded football designed ones and I just want a colored (preferably white, gray or black) cover to protect my psp.
