Memory Stick Duo to Compact Flash conversion

[telekinetic]

Hey forum,

I just bought two 4gb Memory Stick Pro Duo's for use in my PSP ($30 a pop, direct from Hong Kong ) and was wondering if anyone knew of an adapter I could use to use them in my Canon Digital Rebel XTi...it would be great to have 8gb of backup photo storage available.

It has a compact flash slot. I've seen a couple Memory stick to compact flash adapters, and Memory Stick to MS Duo adapters are pretty common...but that seems like a pretty clunky way to go.

Is that my only option (also, is that even an option?) Anyone ever tried to do something similar?
