Good DMM

If this is for a general shop environment, just get a bunch of these cheapies for $2.99 each and sprinkle it around. If someone wants it more than you do, no great loss. It'll do pretty much all you need to do, except maybe high current measurements beyond 10A, but it's probably a rare occasion that you'd need that. Test leads are short, switches are cheap feeling, and it won't read properly when the low battery indication comes on, but 99% of the time, it'll do the job. If you're getting one that you can keep under lock and key, it'd be worth it to get a nicer one, as your budget permits- in no particular order, I like features such as a fast continuity beeper (some have a lot of lag before sounding off), quality silicone test leads, 20A current range, analog bar graph for looking at fast moving signals, on/off switch independent of measurement mode switch (rare- I never did like the rotary switches used for On/off, but even my Fluke 88 uses that- I just prefer a pushbutton on switch for a quick voltage measurement rather than having to flip the dial around every time), frequency measurement, diode check mode (common), selectable autorange, backlight for display, shock resistant housing, etc.. Accuracy probably isn't an issue since it'd be rare that you'd need more than any DMM could provide. Harbor Freight $2.99 DMM
