I was shocked that eBay has only one. It's new and the guy wants 127. WWBW want's 109.
Two completed listings on ebay that didn't sell for 50 and 80.

A couple years ago this was pretty popular. I guess not anymore?

Those prices sound about right.
They are very good for an off the shelf mouthpiece.
