Can anyone suggest a good coffee grinder?

The best I’ve come across (online and not having tried it) is the $150 KitchenAid burr grinder. Lesser priced burr grinders clog periodically, so unless someone else here knows better, you’re probably just as well getting whatever’s at your favorite store.

For sure get a burr grinder; crushing the beans is much better than chopping them. I did a bunch of research to find the most affordable good one, and came up with the Capresso. It has served me very well for about three years so far – no clogs.

Burr grinder, I’ve got a Mr. Coffee. Cost under $40. Works great.

I have had very good reliability with Krups equipment. Their burr grinder works well.
