My experience with supers is that it is hard to get what you pay for. In the little domestic machines, you're paying well over $1000 for a $100 grinder in a box with a brewer that isn't worth $200... The rest of your money is going in to the convenience of having the machine make a mess and a sub-par drink that should be consistent. Like a McDonalds meal. It's neither good nor fairly priced, but it's convenient and you always know exactly what it will be.

You pay for the convenience and forego excellence. Super-autos have a place in the commercial market where they can be enjoyed to some degree by everybody without anyone knowing much more than how to push a button. Not so much in the domestic market, at least in my opinion. I do meet people daily who love their super-autos, often they've never known any other machine and usually they are drinking sugary milk drinks to which their super-auto has added a small amount of espresso.

In today's market it is all but impossible to get a domestic super-auto that is plumbable. Many manufacturers of the very good domestic super-autos have dropped the class and only focus on commercial supers. There's a lot more money to be made putting two Schaerer Coffee Arts into every donut shop across the country than dealing with domestic machines that the owner decided to shut off mid-way through a descale because it was taking more than 10 minutes.

Some higher end manufacturers make it difficult to buy simple parts. They'll sell you a complete brew unit, but not the 6 o-rings with which you could rebuild your old one. But swapping a brew unit is more convenient than rebuilding one, you can always pay for convenience.
