Received a Infinity conical burr grinder a couple years ago. It will make common whole bean coffee(store brand, 8 O'Clock, Community Coffee) have a more complex flavor. Grind fresh every pot and you will see the benefit. When I order some custom roasts from Old Bisbee the results are fantastic. The grinder you have a link to, is not a conical burr grinder. A conical burr turns slower and thus creates less heat when grinding, preserving coffee flavor.
