If precision and consistency is what you are looking for then the GS3 is everything you could want in an espresso machine.  The GS3's electronics, solenoid valves, and flow meter make it possible to program everything: pre-infusion times, rest time, water volume, pressure, and temperature.  These controls give espresso enthusiasts the ability to extract subtle flavors from the coffee every time.  As with other La Marzocco machines, there is the option to plumb the machine or run it directly from the 3.5 liter water reservoir.
