Experience has shown me that you can reasonably purchase good, working test
equipment that's well within calibration tolerances if you are buying the
more 'common' equipment, 6.5 digit meters, frequency counters, even a
Stanford SR620...

I've been very lucky with those, two spectrum analysers and various other
bits of test gear I'd never have been able to afford any other way, saving
thousands over what even tatty examples from equipment brokers would have
cost.

Yes, you can get bitten and buy a complete POS but you can also take
sensible precautions and get bargains.
