I read the note about the Altoids cases, laughed, looked at one I had sitting around, laughed again... then I went looking for the "real" cases around town and couldn't find any, or had to buy as a pack with other accessories I didn't want. I came back, cleaned out one of these Altoid Sour cases, and it works great. I used the cleaning cloth that came with my PSP in the bottom just to keep it soft, cut it in half to use in two cases. There's room for 2 UMDs easily, and you can get a third to fit a little tight, or a fourth to fit tighter than I'm comfortable with, but I'm using the extra space for a spare memory card I bought. I found a 6-pack of these at Costco today for 7 bucks. Good deal :-)
