Good solution, David !

JIC I haven't beat Enco's drum recently; they almost always have a dial
indicator set on sale for under $20.  Today, P/N NW625-1845 is on sale for
$17, which includes a 1" travel .001" indicator and a magnetic base.  And
they do ship internationally for a reasonable price; frequently cheaper than
buying locally for those in Europe.

Of course, it's not the same quality as a Starrett or Mitutoyo; but I've
been quite happy with mine. 

NFI, etc.
