The Durst 138 has adjustments for the adjustments, all over the place. You just don't see materials
and machining like that any more. But these things often cost $15,000 or so when they were new.
But they were also marketed for industrial use, and a lot of the ones out there have taken a lot of
wear and tear over the years. I takes some patience to find one in good condition. But if you have
the opportunity, you should at least look at one to appreciate the quality of the original manufacturing. A vintage Durst is like a Ferrari. A Beseler or Omega is like a Chevy - works fine, but
not even in the same league.
