My daily driver is a $10 Harbor Freight digital multimeter. I'm careful, but if I smoke that thing it's not a real loss. I have a Simpon 260 that I use almost as much. In troubleshooting things the Simpson is essential. If you have a situation where the value (V, mA, etc.) is "bouncing," all you can see on an inexpensive DVM is a chaotic mess of ever-changing numbers. An analog meter like the Simpson responds more slowly to the bounce and you can readily see the high and low values.
