Great! But, what about the TOUGH one? Resolution is easy,
repeatability
is harder, and you need both of these before you can even talk about
ACCURACY. I note that a lot of the lower-cost digital calipers are
not rated AT ALL for accuracy. I got an $80 Chinese-made caliper, and
it is less accurate than a VERY heavily used dial caliper that I've been

(ab)using for years. The error is only about .002 - .003" at the worst,

but that is significant.
