I can put in another vote of confidence for this one. I have one from Portugal (because I
didn?t know about the this-side-of-the-pond source) and it works as advertised.

That is an authorized Bob Parker variation of his original Dick Smith ESR meter kit. On
this side of the pond they were made by Anatek until the owner was killed in an accident,
then the series (now called the Blue ESR) is made by Alltronics and sold by dealers such
as I. These all use Bob's licensed code, just different box and PCB layouts.
If you want a Blue ESR I sell them on my web site's catalogue section, or you can
order the EVB from Portugal if you are on the east side of the pond.
I've been selling variations (evolution by intelligent design) of Bob's ESR meter
kit since 1999!

That is great info, thanks!
Question - I could be mistaken, but I think someone mentioned that these were not good
for testing caps that had a higher operating voltage. Is that correct? My understanding
was that the testing method used by this ESR meter was valid for most all the large
electrolytics...?

As for testing large capacitors, about the highest value that gives useful readings is
around 10,000ufd. Larger than that and the ESR is too close to zero ohms unless the cap is
really bad...
One other unmentioned (I keep forgetting to add it to the list) benefit to the meter is
it does read down to 0.01 ohms which can be handy when looking for shorts.
