I've had excellent luck cruising pawn shops; sometimes the shop has no idea how much a multimeter is worth. I've picked up a Fluke 73 for about $30, a 115 for $50 and a 179 for $70 - all in excellent working condition if a bit dirty. But the dirt comes off and they're all clean inside. In my experience with Flukes, as long as the display works (obviously a condition for purchase) the meter has been in spec. There's currently a glut of 323/324 meters like new in cases around here, though not at such a good price. Not a bad way to get into the yellow cased meters without going bankrupt.
