A few months back, I purchased a coffee grinder, as my old grinder wasn't cutting it anymore, and cleaning the blender after every brew was a little much. So I bought a Breville BCG450XL. It's a conical burr grinder. It holds ½ a pound of coffee beans. I suppose you could grinder other types of beans if you feel the need. It's really been a champion performer for making genuinely good coffee. And though burr grinders are more expensive, they sure beat using a crank operated coffee grinder.
