I am using a Sandisk M2 with MSPD adapter in my PSP and it works fine. However mine is 4GB, but i think it shouldn't be a problem. Better to get M2, since later once your M2 is no longer big enough in size for your usage, you can still use it for memory in your Sony Ericsson phones

Brother, this one rules over all of the cases out there, but unfortunately, play-asia doesn't sell them.

You want something extremely slim (just to proctect from scracthes, grime and fingerprints) because the thick casing gets in your way and affects your playing experience. Just ask around, many people will tell you they rather play without the thick casing.
