PSP Memory Stick to Memory Stick Duo adapter

This isn't the first device that'll let you use regular old (and cheaper) MemorySticks on your previously Duo-only PSP, but it is the most practical so far — even if it still leaves a bit—ok, well, a lot—to be desired on the design side of things. PSP Hardware's selling these for $25US a pop, and say it'll even work with 4GB Memory Sticks. Now, can someone pretty please with sugar on top rig an SD or CompactFlash adapter?
