Why are conical burr coffee grinders so expensive? I was looking to purchase one, but it seemed to me the most expensive than any other grinder.\r\n\r\nAre they easy to use and to clean?

Higher price means better quality. I think these grinders can make good grind.

Conical burr grinder use a conical shaped grinding surface that allows me to select a wide range of consistent grinds from powdery to very coarse. This is why it is the best quality grinder.

\r\n\r\nCleaning of conical burr coffee grinder is more difficult than other types of grinders.

I have the brushed chrome Capresso Infinity and it's a breeze to clean. Simply empty the bean bin, click it out of place, remove the top burr and clean with a vacuum. I also use a small brush, but I can have it completely cleaned out and re-assembled in maybe 5 minutes. Later!
