I think I'll buy another used but operative unit. Prices seem to run in
the $40-60 range. If it lasts another three years I'll be happy.

Just curious... Why would you want to get a second-hand, unknown history
instrument for $50 when the difference to a new instrument is about as much
as one long flight?!? You are going to rely on that instrument for years to
properly run a $15000 engine in a $40000 plane (guestimates..), why not get
a new one that will probably last the remainder of the plane's life??
