Pawn shops can yield an used Fluke 177 or 179 in the $100 USD or less range.
Ebay, for patient, buyers can also yield the above in the $100 USD or less range.
Also, check your local craigslist, local ads, etc.
BTW, try to avoid the parts or "as-is" listings. While some can be repairable, the Fluke 170 series are all software calibrated (i.e. no pots) and the cost of calibration is around the $60 to $100 negating any savings.
For buying new, only buy from authorized Fluke dealers (check Fluke's website) in order to get the "lifetime warranty" aka 10 years minimum.
