For espresso purists out there, a Quick Mill Alexia with a PID interface installed might be the best of all worlds -- not only do you have excellent temperature control of the single boiler when you have the PID involved, but the Alexia also offers the patented E61 brew group technology, which significantly improves the shot. A step up from the Rancilio Silvia and not quite into heat exchangers, the Alexia is a great choice for espresso shot and Americano drinkers -- of course, you also have a powerful copper boiler for steaming, if necessary, but you'll still need to temperature surf on this baby between steaming and brewing.
