Help! I'm in the process of buying out a coffee shop. Inventory has a La Marzocco 2 group- listed at over 9k! This machine is approx 4 years old and has broken down 2 twice in the last month. I know it's a great machine- but I imagine this must be the "new" price. The alternative is a 2800 Rancilio- l year old- for approx $2500. Anyone have an idea what the going price on the used Marzocco might go for???
