I got a nice one at radio shack a few years back for $35. It was cheaper in the store than it was online, and had pretty decent reviews. I think they are around fifty bucks now, maybe a little under. The # is 22-812. It can be linked to a computer for data logging, although I've never tried that yet. It has auto and manual ranging, measures voltage, current to 10A, resistance, temperature (no probe included), frequency in hz, diode test, and a couple other things too, I think. The only reason I would spend more is for true RMS measuring abilities, or if I was in the electronics or electrical trades. A decent clamp meter would be handy for measuring higher current, but not totally necessary. I have a bunch of the cheap HF digital meters, and for the most part, they are pretty close to my Radio Shack meter. They are fine as long as you can check them against a known source or another good meter.
