I have only ever seen one for sale in the U.S, but they do occasionally come in from Europe. The one that I remember seeing was for sale with a very high end collection (think Fierce Snakes, Fea's Vipers, etc.). This animal was priced at (I think) 3,000 USD. You may be able to find the advertisement on the Southeastern Hot Herp Society website. I saw the ad about 2-3 years ago (approximately). I haven't seen any available to the public since.
