I have a Gaggia Brera Super Automatic which has a bean hopper and grinds the beans fresh for each shot. All you have to do is turn it on and press a button. Every few days you just add more beans, refill the water reservoir and dump out the grounds collection unit. I paid $400 for it 3 years ago and the only maintenance it requires is running decalcifier through it every few months. If you're a regular coffee drinker, I'd say it's a worthwhile investment.

Yes but Keurig isn't really espresso, it is similar to traditional brewed coffee just with some alternative flavor choices.

I guess Keurig is different from the espresso capsule machines. My machine is a locally licensed K-Fee compatible device and there are both brewed coffee and espresso capsules available. The brewed coffee capsules have some kind of mechanism that prevents the usual espresso crema from forming (I suppose by depressurising the water flow).

A stovetop espresso machine takes maybe 30 seconds of active work
