Looking for a source for gtx 295's

I'm still new to this forum so excuse me if this is hthe wrong place for this post (mods feel free to move it if need be). I am trying to source a vendor for a few gtx 295's for CUDA work. Since they have been discontinued for quite some time I'm having a problem locating any.

Does anyone have any thoughts on where to look?

Thanks again.

This may seem very obvious but I'd start in the "For Sale" thread, I've actually seen a few listed here over the last couple months - worth a shot anyway!
