If I recall correctly Brian, the TX series had some basic design flaws in it's valve-train of some sort which caused it to be pulled from the market after only a couple of year.

(but as I said, I may have my facts wrong about that or I'm confusing it with another model of theirs)

Yep! Just like a good Single Malt Scotch, you might call me "an acquired taste" TOO.(among the many OTHER things you may care to call me, of course)
