Verion ACS are very good on the support for their machines in terms of sending out parts and giving advice. Plus the Minima uses many industry standard parts for the things that commonly go wrong to espresso machines. e.g. vacuum breakers, safety valves, solenoids etc.. The main advantage is the solenoid E61 group which is not maintenance needs at all, can be backflushed weekly and has almost nothing to go wrong….just 1 solenoid valve, and those can last a very long time indeed.
The Minima has a huge amount of performance for the price…steaming better than many machines around, espresso shots are great as it has a nice smooth and gradual ramp to pressure.
If you are not willing to do any fault work yourself though, then buy a machine from a UK supplier, but be aware shipping a machine back and forth for fixes, is a non trivial risk.
