I went with an Atlas ESR70. It should be about $100.

The cheap Chinese 328 version works great! And this is coming from a guy whose
engineering career was spent designing test equipment.

One thing to know...when using any of these ESR meters be CERTAIN
any caps you test are fully discharged and remove all components
before testing. They are easy to frap.

These are about the very best bang for your buck.

I have an expensive chinese LCR meter for about 3 years... I've used it maybe twice.
I honestly don't see the value for the average hobbyist ... Caps are cheap; just replace them if in question.

I also have an atlas and basically all it does is tell you the esr of the cap you’re putting in is worse than the one you removed.

I have two of them

And I always test capacitors just removed. It will save you time from ordering and waiting for replacements only to find they weren't the problem.

These are good not only for caps but transistors and diodes.
More useful in fact for these as you can identify parts that
have degraded but haven't failed completely yet.

This post is right up my wheel house ....we had a lot of caps in FAA navigation equipment and I did years of research on ESR and Caps. Basically you need to do three tests on any cap to tell you if its any good . Capacitance , leakage and ESR. Many caps right out of the pack will fail ESR and capacitance until you form them ..which is basically bringing them up to their rated voltage in 5v increments and then letting them sit there for 30 min to an hour. The electrolyte inside the cap will eat away at the oxide coating if it sits on the shelf for a long period of time . By forming them you rebuild that coating and many will pass after this process. Many times if it doesn't pass the capacitance test it won't pass ESR so just having a capacitance testor will tell you a lot. If it still doest test good after forming it is definitely bad. Leakage is another easy test by hooking a resistor to limit current draw to the cap under test and bringing it up to voltage ....when brought up to voltage it should draw no current . ESR is the least important test but still nice to know as long as you have the cap specifications for what the esr is supposed to be on the spec sheet. You can get a cheap esr component tester off ebay that work well enough handle most components in a pinball machine or stereo

People seem to think they don't give you the right capacitance number but the fact of the matter is ....the cap rating is the minimum capacitence but it could be higher (which means you got a better cap then expected ) and most of the time the cap will read higher then the rating and people fault the test unit which is not the case

The component tester is also an indespensible tool for transistors, mosfets diodes etc

For caps I spent my money on a good capacitor tester with inductance for checking coils and all you need for leakage is a bench power supply
