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.

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.
