If you have the time, I'd appreciate if you voted in this poll. I'd like to get a sense of your need and use of low resistance micro-ohmmeters. Thanks.

I have used high-current versions a lot for measuring bolted connections on busbars and contacts on breakers. I have used them on motor and generator windings but you are getting more into the milli-ohm range and the test current gets reduced, although some manufacturers have brought out high current units to meet these demands. Earth testers also use the 4-wire resistance method as well, but again milli-ohms range, they can both AC and DC. Finally, I use battery resistance testers, such as the Hioki BT3554 that I reviewed some time ago, again more in the milli-ohm range and uses AC rather then DC.
When I hear micro-ohm meter I think of those 40A continuity tester boat anchors not something like
We use micro-ohm meter for testing quality of Through hole plating in PTH double sided PCB.
