No direct experience, sorry. I do have a shunt from the same generation (few precision power resistors and some switches), which works fine. I think $90 is a bit high, you can get something like the HP 3468A for less, and it'll probably have more features and better specs (except display). Note that ACV and resistance are optional (these are installed in the linked ebay auction), and you need an external shunt for current. For $90, it should be guaranteed working with returns accepted and have all relevant options, and even then I would probably choose something like a HP 3468A/3478A/3455A/3456A, or Keithley 192/195A/199, unless you're doing it for the cool nixies.
