   Another good choice is:

Their selection of tooling usually includes choices between
American-made and foreign made, so you can pay for the quality you need and no more.  Not that some foreign tools
aren't every bit as good as U.S. - it's tough to beat the
quality of Mitsutoyo instruments - but QC on tools from,
say, India won't be as good as from well-known U.S.
manufacturers, so the quality can vary significantly from
one month's production to the next.
