Description from Seattle Coffee Gear
Sturdy stainless steel casing, brass components throughout and an upgraded commercial-grade steam wand make the Rancilio Silvia Version M one of the most popular machines on the market. Simple, reliable and powerful, the Silvia espresso machine produces excellent espresso and silky microfoam milk for your lattes and cappuccinos. Add even more consistency to your Rancilio Silvia with the addition of a PID controller. Installed by our own Seattle Coffee Gear tech department before the machine goes out, these units enable you to control the temperature variance on this machine by as little as one degree.
