Micrometer.
Vernier caliper may also work.
Either under $30US.

I don't believe anyone uses vernier calipers anymore. I've got a Helios
dial caliper made a long time ago in Deutschland, but nowadays a caliper
with a LCD is probably a lot cheaper.

I do.

I haven't got a LCD one, but a magazine sends me one every year.
Ok, it's made of plastic, but it works fine, and is accurate enough for
me, seeming to be within about .05mm

I'd like an LCD one of course.

You should shell out the $20 or whatever then (or $100 and get a
Mitutoyo or other brand name with a bit better "feel"). I use mine all
the time- for rough (0.001") width, diameter, inside diameter
(rougher) and depth measurements. A micrometer is useful for precision
measurements, but less necessary for an EE.
