I just retrofitted my basic hand crank mill with a 10mm nut, and drove it with a drill. It's so much faster now, but I do wonder if there's actual properly motorized versions of what I just did.

Capresso Infinity. It is an inexpensive conical burr grinder. I bought mine in 2012.
Mine lasted about 4 years before the thermister died. I replaced it with a 1Ω resistor and it works no problem. I've had to replace that resistor about every 4 years, three times so far, most recently a couple months ago. I would guess it is there to limit heat in the motor but the motor has not yet failed so 🤷.
I grind 60g of medium fine or 40g of coarse just about daily and it has otherwise held up fine. In the summer for the last few years I grind 120g of coarse every few days for cold brew, that is a longer grind and probably the most risk of overheating but hasn't really affected the life AFAICT.
You may be able to spend more on a grinder that lasts more than 4 years, but this is a cheap and easy fix if you're handy with a soldering iron.
