I am considering pulling the trigger on a used VBM Domobar Super 2B/Compak C5 combo. It will be for my 2nd home where I will be spending less than 10 days every month. It's not like I will have the time to drain the boilers for storage every time I leave. Will it turn out to be a maintenance nightmare? I've never owned an E61 type espresso machine before so any insight will be much appreciated. Thanks in advance.
