I am getting into espresso making at home and wanted a machine that offered a lot of versatility. The Dual Boiler was a perfect middle ground between a fully manual (and very expensive) dual boiler espresso machine and a semi-automatic (or fully automatic) machine. This model is basically a manual espresso machine with dual boilers and automatic control over the temperature, pressure, and shot duration (all customizable). That leaves the grinding, dosing, and puck prep to me, the user which is just want I wanted. The price on the set (Dual Boiler + Grinder) was actually LESS than the cost of the Dual Boiler alone. Could not pass that up! While the grinder is not the best, it's definitely usable until I can afford a better one.
