If you want to be able to easily measure very high DC currents, check out the Sears Craftsman #82369 digital AC And DC clamp on ammeter for just under $60.

This allows measuring DC currents in two ranges, 0-40 Amps, and 0-400 Amps, simply by clamping the meters jaws around ONE of the battery leads. Also note that most clamp on ammeters are AC only, not useful for our stuff.

I've got one, and take it along to the flying field whenever I go there. Makes it easy to check other members electric setups without needing adapter cables and such. This meter also has the usual resistance, AC and DC voltage, frequency, and even has a thermocouple type digital thermometer.
