The best DMM I have ever used (and I still do use) is a Beckman Tech 310. It has not been made for probably 15-20 years, though.
I have a few of the Harbor Freight DMMs that often go on sale for $3 each, and it is certainly usable for basic stuff.

Don't bother with the $3 Harbor Freight meters, I don't think they can even measure any resistors over 1 meg (the $20 model will do up to 20meg).

As for the $3 HF meters, I have about 30 of them, all "MEET USA" brand - got them in Dubai at their 5&10 store. I paid 5 Dirhams each, or about $1.36 each, with an alkaline battery that was actually pretty good. I checked them for accuracy - 50VDC from my Fluke 332B measured +/- .5V, or about 1% basic DC accuracy. AC was off by about 3-1/2% at 60Hz, and 12% out at 400Hz. Resistance is the worst, about 10 percent off across the board. Still, they are ok for measuring use with the truck, or as a go/no-go tester for Christmas lights. I've yet to toss one out, which is what my original plans were should one fail. But for regular use, these are useless. Cheers,
