I wouldn't call them "good", but you can get a basic DMM from
Harbor Freight for $3.99 and they have others from there.
I have 8 of them for my lab bench where accuracy is not the
biggest deal, so I don't have to use the better ones up.
My primary beef with these is the current range series
resistance, which is pretty high at the low currents. You can't
change range without changing circuit, basically.
My favorite meter is one I got on sale at Radio Shack,
with thermocouple and frequency reading.
