I am looking to measure caps in circuit ...
No ESR meter whatsoever will be able to discriminate two caps in parallel in a circuit. On the other hand, the simple
meter based on Atmega328 does a very good job for in-circuit measures when its possible.
You have to be cautious on the interpretation of the results, but it is very useful.
but would have to use chinese panel meter and not sure quailty for the intended use???
If you take a kit like this one,

(in China of course, as most of the PCB for hobby use are made there)
The design is not from China, and is totally documented in
http://www.mikrocontroller.net/wikifiles/8/8f/Ttester_eng111k.pdfRight now I more or less a basic understanding of electronics and wouldn't even know how to find parts that would match and the circuit not modded..
To build the kit and try to understand how it works by reading carefully the 103 page documentation of
Karl-Heinz Huebbeler, will definitively improve your knowledge in electronics.
You will then be able to make your own improvements in the hardware or software (which is also available online).
I would advise to first use the provided already programmed Atmega328 chip, and then make your own experiments on a
new chip that you program by yourself.
