This fellow I picked up some cheap palladium on carbon from on Ebay has been trying to sell some other catalysts, but hasn't had any takers yet.
These prices look awfully good to me, but I'm not looking for any more catalysts right now.

He's also got some good prices on a jacketed 14/20 short path and a jacketed silvered 14/20 Hempel column.
If you contact him I'm bet he'll re-list it.
