Adam, check out Alfa Electronics - they carry an excellent set of very
inexpensive meters.  Their DMM-20  measures AC, DC voltage to 750 volts,
resistance to 2 gigohms, current to 20- amps, CAPACITANCE and
INDUCTANCE, frequency  from 1 hZ to 15 mhZ, has a built-in transistor
and diode test, continuity beeper, and overvoltage protection on the AC
and DC ranges.  Sells for only $74.95!  Order number is 1-800-526-2532.
I have bought two of these for friends, and I bought an LCR meter from
them for the same price.  Delivery was fast, and everything has worked.
