I don’t know how much you’re willing to pay, but if you can find it for its original price ($50) then you are doing well. I know of two places to look: BoardGameGeek (BGG) and eBay.
As of today (20200919):
BoardGameGeek has two available, $150 in the US, Euro 85 in France.
eBay has one available, $190 in the US.
I hope that helps.
