La Marzocco's GS3 dramatically resets standards for performance among home and light commercial espresso machines. Borrowing many of its features from La Marzocco's commercial espresso machines, the GS3 compares favorably to the finest high volume machines on the market today. In a tiny footprint, with water reservoir or plumb-in options, GS3 suits home use and has sufficient steam power and performance recovery for many commercial applications including restaurants, catering and professional offices.
