Fluke meters
My local surplus store had the best deal I've gotten there this century, a box of medical surplus Fluke 8062A 4 1/2 Digit TRUE RMS Digital Meters.
I bought the box, powered them up, tossed quite a few of them, after testing each unit as follows:
Using a DC constant current source, I tested 0-200 mA and 0-2000 mA ranges.
Using a DC power supply, I tested the 200 milliVolt, 2,20,200 Volt ranges
Using a wall outlet, I looked at 110V ac on the 200V AC range.
Using a 10 ohm resistor, and a shorted pair of test leads, I checked the Ohms ranges.
Watching the boot test, I checked for all display segments dark black.
If you need a specific test beyond that, just ask.
These are nice, if you pop the lid, there are individual range calibration potentiometers and a field cal procedure instruction sheet installed. They are fused on the inputs, and most of them come with spare fuses in the battery compartment. Nice internal shielding, these are very solid meters.
Ideal for calibrating Diode Drivers with the 200 and 2000 mA ranges. These are the LAST of the high end Fluke Handhelds made in the USA, and are Quality. Not many handhelds actually have serial numbers these days.
Surplus test equipment places are getting 60$ for these uncalibrated, and about 80 if they have the calibration procedure done.
The downside. The medical people removed the battery doors as a sign to show these are not to be used in their plant when they bought new meters for all their techs. The upside, the way they are built, the battery is retained without the door, and with a bit of velcro and sheet plastic, and a few minutes of your time, you can easily make a door. Not that anyone would ever know the difference. I'm pretty conservative with my tools, and I have two riding in the field kit in the car sans door. Unless your very vain about your image, most people would not even care.
Other downside, leads not included but standard banana and shielded banana leads fit.
Here is the Fluke manual:

This is one nice meter, and Radio Shack sells a decent pair of leads for $6.99. You cannot get true RMS at Home Depot these days, nor the accuracy these provide.
I have 6 for sale at 35$ each plus shipping, I imagine they will fit in the Postal Priority box. Note the that 1.50$ of that will probably go to buying foam for the shipping, so that is not a bad price.
Find a DVM you can get these days where the manual actually includes a schematic!
