People aren't "cashing in" on his death. The price went up long before that when Grok stopped making them. It's supply and demand. End of story.They did and anyone is welcome to buy it at the asking price. I can't imagine why anyone would want it though? It is nothing special and can do no more than a TecMate, Carb Tune Pro, Twinmax or any other balancer will do.
IMHO, a lot of sellers are trying to cash in on the death of the inventor of this product. Very greedy and sad.

You've bought a lot of accessories for your bike, you do realize that they cost a fraction of what you paid to make, right? For example, the Wunderlich adjustable shifter probably cost about $50 to produce. But no one else sells one so they can sell it for $220.95....
