DIY test leads - source for lead ends?

[OpenCedar]

Is there a recommendation out there for test lead ends? I'm pretty disappointed at the quality I am getting from random sellers online.

It must be quite common for a lab to need to make a custom lead, where do you go for those pieces so you know they are made of what they say and you can count on it in your results.

Thanks in advance!

If you're talking DMM probes, I have accumulated dozens of
sets over the years and they don't wear out. I've soldered
sewing needles to some, for special-fine poking, etc.

Pomona is a very broad line source for connectors and such,
higher-end quality IMO and priced accordingly (widely avail
at distributors, and on eBay).
