You won't go wrong with a Fluke, any model. There are LOTS cheaper
meters, but none much better. The biggest deficiency in the cheaper
meters is that lots of them are very low input impedance. Absolute
accuracy is really not all that important for 99.9% of what you will
use it for, but low input impedance can be a problem, especially if
you are working on tube type gear. Look for at least 10-11Megohm
input impedance.
I second the Fluke DMM recommendation, and have another to add...
Look around for a good analog meter to add to your workbench; they're
very, very useful to have around as well, especially if you're doing
any kind of fine receiver tuneup. It's much, much easier to detect
minute swings of a needle as opposed to the often constantly bobbling
numbers on a DMM display.
I highly recommend the Simpson 260. I picked up a near mint Simpson
260 Series 6P, complete with the original Bakelite case with roll-up
door, for $50 at Dayton a couple of years ago, and it has made
receiver tuneup so much easier. I had almost forgotten how nice it is
to use a really good analog VOM...
The real bonus is that the Series 6P and later models used one D cell
and one 9v cell as opposed to one D and four AA cells. Much easier to
change batteries, although that wouldn't have stopped me from buying
one of the earlier models.
