If you're interested in a small kit lead wise, you might want to consider Probemaster (i.e.
8043S). Granted, they seem a tad expensive on the surface (~$30 shipped), but keep in mind that either the Pomona or Brymen set run $17 just for the leads shipped. That extra $13 gets you 6x top quality connector ends to go with it, which typically run ~$5 - 7 per, if not more from Fluke/Pomona for example.
Quality wise, Probemaster is right up there with Fluke/Pomona (arguably better vs. current production), but offer a better value IME, at least for those in the US (not sure they even have overseas distributors). Oldaker is another (harder to find, but also very good stuff), along with Mueller and Hirschmann. Again, not cheap, but as the old saying goes, you get what you pay for.
Agilent isn't as nice (16AWG wire that has memory vs. 18AWG used on Probemaster, Fluke, or Pomona that doesn't have any memory at all; think fresh spaghetti noodle kind of flexible), nor are their connector ends as nice IME (small details, but that's what it comes to at this level).
Franky is another alternative for value priced quality connectors and leads, but I don't recall any sets offered thus far. He might be willing to offer some if there's enough interest, so could be worth inquiring.
