After years of struggling to calibrate my multimeters for voltage, I found an $8 voltage reference on ebay from China.
ebay link
It provides a 10.0 volt reference. It came with a calibration record so the seller is at least aware it needs to be checked.
Incidentally, the same seller has a little flashlight with a Cree LED. I've heard folks on RV.net say the Cree is the best, so I bought one of these little 1 AA battery flashlights for $4. I am very impressed with its brightness and apparent quality.
