Passon or Tremec TKO 5 speed gear box consideration.

In the other thread about the Passon 5 speed someone posted about future parts availability, to me that was the nail in the coffin at ever buying one. What are the chances of getting parts 10 years from now when they are having trouble producing them now, plus you are relying on a one man business to stay opened in order to have any hope of parts support in the future.
They should have sold the design 5 years ago and worked out a royalty deal with one of the larger transmission builders and they would have sold 1000's of them already.
