La Marzocco GS/3
Single-group, dual-boiler, PID-controlled, powerhouse espresso machine.
La Marzocco's GS/3 dramatically resets standards for performance among home and light commercial categories. It compares favorably to the finest high-volume machines on the market today. In a tiny footprint, with water reservoir or plumb-in options, GS/3 suits home use and has sufficient steam power and performance recovery for many commercial applications including restaurants, catering, and professional offices.

Available in both Automatic-Volumetric and Mechanical Paddle (shown below).
