I have for sale a La Marzocco swift grinder with ceramic burrs (about halfway through their life cycle. A few minor scuffs on the exterior but still works like a dream. Professionally serviced after being taken out of the our cafe. It's a double hopper, double motor grinder. Each side is run independently and can be individually programmed. Not just for la Marzocco. I've seen these used for Rancilio's and Spaziales as well. Just do a bit of research if that's what your outfit uses to learn how to run those portafilters safely and with precision. Asking $2200. You pay shipping.
