If you are a weekend troubleshooter I would pass on the AC clamp on meter. A DC clamp on meter is going to be used more often.
A Fluke multimeter is fantastic. You can get a clamp on DC meter that has the voltmeter functions built in. I keep mine hanging on a nail with the probes dangling so I can take measurements on things on my work bench.
So one meter does it all.
Keep a cheap "analog" meter too. One that has a needle swing that is. You can get fooled by a digital meter so cross referencing with the cheapie unit will help sometimes.
