Well, the coffee grinder is a must-have kitchen appliance in my eyes anyway. Not so much for coffee, but spices, whole grain flours, breadcrumbs, and nut flours.

I can see spices losing their spiciness if ground and left sitting. But you notice a difference w/ the other stuff?

I just bought a cheap coffee grinder - three level (fine, med and coarse).

Should I have bought a better one w/ 18 levels?

Have you heard of cheap ons breaking? What is he difference...bc I can't see why you would need 18 types of grinding evels? Are some coffee beans harder than others?
