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.

I lucked out and got a MIB Beckman 4410 - their TOTL True-RMS "handheld" - from a eBayer - for $13, including shipping! It eats batteries, but I love the 4-1/2 digit display. It's one use is measuring those tiny 1% resistors. I hate having to figure out the colors - is that red or orange? Measuring a 1% resistor is a breeze with it. I use my Fluke 75 for 99% of my measuring needs.
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,
