I'm using one of these:

I would look for a device with a needle rather than
a digital readout.
I don't think you can measure true rms with a coil and needle. :-?
It was measured by thermal effects...

For example, the Balantine 323 has a nice big dial. You would have
to measure the voltage drop across a known value shunt resistor in
series with the load, and calculate the power from voltage and
current.
