First off, this is my first post ever on the digitpress forums, so hi everybody.

Down to business...

This morning a customer at my store traded in a "Dual Analog" controller for the original Playstation. Not the DualShock, but the original, apparently very rare, "Dual Analog".

It's the USA version, not the Japanese one.
Anybody have any idea what these things are worth? I can't find anything on eBay, so any help would be greatly appreciated.

Thanks in advance guys.
