Synesso, Inc is the American maker of "temperature stable" machines. Founded by Mark Barnett who was formerly the research/designer at Trueh. These fine machines offer perfect temperature control on a brew head basis. This means your first pull is spot on. There are no temperature fluctuations to ruin your espresso. It also means you can offer different espressos that need different brew head temps. While you do find totally hi-tech pid temp controls the brew button is manually controlled as is the classic steam wands. The Synesso machines are definitely for those who appreciate and understand the artistry required for exceptional espresso quality. Visit Synesso.com here.
