In the late 80's, I made bread every other day, hadn't started roasting coffee yet, but was buying from a local shop that did every day and grinding the coffee in a hand powered mill.
I wasn't 30 years old yet, but arthritis had started to take my hands. Realizing I wouldn't be able to do many of the things that brought me joy, I started buying commercial quality appliances.
Woke up at 02:30 today, put a pot of coffee on and started a pot of onion soup. While grinding the coffee, I thought... I've had the same burr coffee mill for twenty years!
When I bought this machine in 1989, girl of the day was sure I had gone mad spending $300 on a coffee grinder. Twenty years later, she's long gone but that machine still works once or twice a day as it has for the last 7,300 days! That's .04¢ a day, you can't beat that.
