I've located almost all of the other card expansions...this one is appropriately elusive.

Does anyone have any suggestions what so ever as to where I might look for a copy of this??

I had to buy my from a shop in Austria, and I'm in the USA. I don't want to confess what I paid for it. Hit the eBays... all of them... and say a prayer to the powers that be. Then be prepared to have your wallet wail a little. You might also check the expansion's page at BoardGameGeek.com. Sometimes there will be link-ins there of people trying to sell expansions elsewhere, either new or used.
