One last note for those like myself in need of a large digital readout DMM.
This one has a 2 inch LCD display with many automatic features. it is geared for the pro auto tech but serves the functions of audio gear testing quite well too.

Do check with the maker for it's accuracy tolerances if that is a concern though I'd think it fine enough for even the more serious hobbyist. For under $100 it's the most fully featured, DMM with the largest display I've found yet.
It could save one some money on auto repairs too if you're into that and can pull yourself away from the sweet spot long enough to go work on the grease spot.
