I've got a bit of everything -
Pomona 5519A - for general electrical work. The probes are like the standard leads that come with most Fluke meters, but the wire is silicone instead of the vinyl used in Fluke's cheapest leads, so they're a good upgrade. I've used them for a long time without problems.
I've also got a bunch of specialty accessories from Pomona - Leads with mini-grabbers on them, push-on alligator clip adapters, and leads with pin probes on one end that that fit in Euro style multi-pin automotive sockets. I think that if I was starting from scratch and was mainly doing automotive work, I'd buy the Pomona modular leads instead of the standard ones, and would then choose a selection of special purpose tips for them. I think Pomona makes more special-purpose probes for automotive use than anyone else.
Probemaster 8017S - for electronics work. The probes are a bit shorter than standard Flukes, and the tips are gold plated and have quite sharp points. These are my favourites for probing pc boards and generally anywhere stuff is tightly packed.
Probemaster also makes modular test leads (9100 series) that are similar to Pomona's. I haven't used them, but I'd give them a look because I like my 8000 series ones a lot. I think that most Pomona, Fluke, and Probemaster automotive specialty tips for modular leads are interchangeable, so you can mix and match between the different manufacturers.
