Hello, I need help finding a good one for my problem. I used to always use a crystal case with my PSP but lately the battery life wasn't enough for me so I bought a larger capacity battery. The problem is, its bulkier on the back and it doesn't fit my crystal case anymore. I've been looking for a casing that is compatible with the larger battery pack but to no avail... Is somebody else having a problem about this? Can anyone link me to a good casing or protector from scratches? Thanks!
