I've been thinking of buying a GAM Check for testing cable, insturments, ect. I have a very nice Fluke DMM that I absolutly love, but I want something cheaper that I can afford to drop. Do you think I should go with a Sperry meter from lowes for about $80 or fork up the $150 for the Gam check. They seem pretty durable, but 150 is alot for a few basic circuits, I could just build it myself I guess. So low end DMM with Volts, Impedance, Amps ( up to 400A) OR a Gam Check ? I use the equipment on a daily basis. What do you guys think?
