Friends of mine put one in their new house 5 years ago and it had the same super auto group/internals as my Gaggia Syncrony Compact which is the same as most Gaggia and Saeco and some other brands of super autos. Sounds the same when making a coffee too.
At the time, mine cost $500 new and theirs was ~$3,000. Yes it had a nice stainless facia and stylish dials that matched the rest of their designer miele kitchen but the end result was exactly the same. You are paying for that design, the name, consistent user interface with the other appliances, service and not necessarily what ends up in the cup.
The new models look a little different and they seem to steam the milk as well, which is probably a step back in my mind. Id be shocked if the end result was much better.
To compare to your Expobar, you should feel nothing but great dissapointment. Others in the household that arent so snobby may see it diffently.
If youve bought the place, Id remove it and replace it with extra storage or some other appliance. If renting, I guess it must stay. Either way, find some bench space for the Expobar and keep enjoying coffee the way its meant to be.
