I'm using a Cuisinart machine with auto on and off, a 1-4 cup feature for "double heating" the water (I'm a chemist and I don't know what that means!), a gold cone filter, water filter and a beep that lets you know when it's ready to be poured. Usually I brew Starbucks, freshly ground, although due to budget constraints I've had to go with 8 o'clock Columbian coffee, which isn't that bad, for the price.
