The Capresso Infinity burr grinder is unheard of, so I googled it and found it. Looks like it has the same Burr and Carrier type arrangement as the Solis 166 - NOT for Espresso, but will work for Drip.
The only grinder in that price range is the Sunbeam EM0480 to do both Espresso and Drip grinding as it is stepped. The KitchenAid is WAY overpriced for what it is.
The Rocky Doserless is an option if you can stretch your budget.
Anyone else got any ideas?
