For what it is worth, I realized that superautos could make good espresso when in Italy in 2000 and got consistently good shots from the commercial superautos used in autostrada plazas. But those machines were serious equipment. Most home superautos I've tried have had a hard time producing good shots. But it can be done.
If/when we redo our pantry I'm going to get a built-in one with a water hook-up. The biggest pain with the one I have now is having to refill the water every few days.
