You know what's happened. It started with a cheap Radio Shack (no longer available). I left it on the SCCA truck for 1/2 a year so bought Greenlee analog that wsan't as good for car work (scales are pain to read), then finally got a cheap automotive focused digital. I use them all! I keep the greenlee at the house for home electric or the car, the digital usually lives at the garage and the radio shack usually lives in one of the cars, preferablly in the tool box.
