Which Multimeter for newbie.

A multimeter (Fluke 73-3) is a part of my everyday life.
Analog meters are still used daily in many shops and there is nothing wrong them.
For home use once every blue moon... there's no need to spend BIG $$$ for a meter. (More than $50 is a waste of money)

I bought a bench Fluke 8050A digital multi-meter (pic) on eBay for $50 three years ago. This is an excellent DMM that is very accurate and durable.

They still sell for $30-50 these days. It is perfect for any DIY project or repairs.

Cheap ($20-30) ANALOG multi meter.
The mirrored needle is more telling than a digital display of small variations in a signal if you should ever venture into more involved... metering(if that is a word).
Why on earth would anyone spend more than $100 on a meter simply to bias a tube amp?

Good luck!
