Going by Newegg prices (seems like a good benchmark), your Pro stick 256 (I assume it's Sony) is $97.

I do have a Lexar brand "regular" stick of 128, which they list for $48.

It's a difference of $49.

Hmm. I have a 5.0 mega pixel Sony P10 camera. the 128's always been enough, but the 256 sounds... well I'm a geek I guess.

If you're interested in a swap, let me know. I'd send you the 128MB stick + cash, and you'd have to just send yours the opposite direction at the same time.
