I bought a cheap one on Ebay awhile back. It is sufficient for my use which is to say it measures capacitors, inductors and resistors in the range for audio crossovers. What I was most interested in was matching components (precision) rather than exact values (accuracy) and this does the job. The accuracy is so-so (plus/minus 2.5%) but the measurements are reproducible and consistent.
It's made in China (naturally) and the model is DM4070 for about $35.BTW if you want something much more elegant the DE-5000 is only $100 (available on Amazon and Ebay) and has much higher accuracy (0.25%) and lots of bells and whistles. I don't have one but the reviews I read give it high marks.

Repeatabilty is the 3rd leg of metrology.
I used to keep track of metrology equioment in an ISO certified facility. I did an ANNUAL study called a gauge R+R in which (short form) 10 samples were measured 3x EACH by 3 different operators.
I had NIST traceable standards for SOME equipment but studies used ALL house generated samples.
I'd get a couple of each of what you measure and SAVE them. Measure them periodically and before any critial use to check 'drift' of your meter.
Too much is never enough
Good advice. It's easy enough to get some 1% silver-mica caps and they won't drift much over time. You can also calculate a resistor to put in series to create a dissipation factor standard.
