I don't think I could ever leave my high quality but high-z meter back in the office in favor of one that gets me less. You can always go high to low. You can save alot of bucks with a couple feet of 1000V flexible test lead, a couple insulated gator clips, a little heat shrink, and a 27k, 2W common resistor. That would put just under 5mA load on a 120V circuit. If that's less current than GFCI specs say will kill you, it should be a good safety test when used with a hi-z meter. Just keep it coiled up in your Fluke pouch. If you get a non-zero voltage that concerns you, just clip the resitor on and measure again. Problem solved.
