My LCR meter has an ESR function though I seldom use it. To be honest I
mostly just use it's resistance range for finding short circuits on
boards. It has a resolution of 0.1milliohms, not that you need quite
that resolution for finding shorts. It has fantastic resolution but
so-so accuracy.

That LCR meter will probably not detect high ESR until its boils your
coffee bad.
The 2 of the 10 dollar ones I bought were shipped Saturday night late. It
will be interesting to check it out, I have several years experience
with the Capacitor Wizard, it made it possible I could keep about 18
Dvc-Pro machines running at the tv station. Each one had at least 500
of Panasonics own brand of capacitors in it, they were smaller than
anybody else micro versions, and a typical repair was maybe 2 of the 14
to 18 boards in it, testing the caps and replacing the shaky ones, per
day.
So it was often that the individual machine was on the bench for several
days. Even with a 5x13" board in a Panavise frame, it was by the end of
the day, back breaking work just from sitting there all bent over. 15
years later I still think thats the main reason I retired at 66.75 yo,
still less than a year from maximum SS at 67.5 in those days.
