Franke Sinfonia

4 used commercial automatic espresso machine/latte makers. These came out of a McDonald's nearby. As far as I know, they just need a maintenance and a cleaning and some replacement parts(grinder lid for one machine and full grinder cones/hoppers with lid for other two machines). My husband purchased them simply because they were for sale but we've just had no use for them. I do not know what they are worth now I just know they are originally expensive machines. $500 per machine or best offer!
