Call me old school, but my analog multimeter has never let me down.
I was fixing a flickering light in a shop, and my digital tester said everything was fine. But the problem kept coming back. I switched to my analog multimeter and found a slight voltage drop the digital one missed. It's bulkier and needs more care, but I feel it gives a better sense of what's really happening. Most guys think I'm crazy for not upgrading, but I stick with what works.
