On ebay there are devices like the Peak that are not in a case but are
functional. They are only about $ 20. They do not rip you off like
Peak in that one device will check the transistors and capacitors
(active and passive components).
I have one and put it in a case. I works very well.

It acquits itself quite nicely against some pretty high-end meters. So on the "pro" side:

a) it is accurate against some industry-standard devices.
b) it is self-contained and serves both to measure capacitance and ESR. Doing two things well rather than many things less well.
c) it will discharge capacitors without damage.
d) it is NOT made in China.
e) it will measure in-circuit and out.

I keep four meters on the bench:

B&K LCR meter
Fluke "true RMS" VOM
Peak Atlas Transistor/diode checker

And the aforementioned meter. In my traveling kit (Kutztown twice
per year, and when 'in the field', I keep a very vintage Radio
Shack Japanese VOM, and the AnaTek ESR meter.

A few Radio Shacks are still open. I don't get into low or high voltage work much, but in electrical class, I remember briefly carrying around those oscilloscopes or those light-blue suitcase-looking test beds with all of those jacks and l.e.d.'s.

I wonder if pocket oscilloscopes now come with test meters and test recievers for resistance measuring.
