As a rule I'm one who always tries to buy the best tools I can afford, but after my experience with the Milwaukee MW102 I bought, I'm tempted to follow Dave's advice. The MW is a total POS, even new out of the box it took anywhere from 4 to 10 minutes to settle on a reading, and can't be relied upon for consistent readings. I may have just gotten a lemon, but based on my experience I can't recommend the Milwaukee meter.
