The Delonghi one will make a single cup. One I had you set stuff such as cup size, coffee strength etc. The beans were just in the top anyway, fill the tank up with water. Pop the cup under, hit a button and your one cup of coffee is done.
Extra bonus, you can have straight coffee or go for a latte, flat white, capp, espresso, etc
They are not cheap, as mentioned, but if you look around you will get a decent deal. Especially if they have put another one out in the market, the older ones will drop in price
