Welcome to CS !
Nespresso is instant coffee out of a machine (of sorts).
I guess it comes down to what you term "good coffee" and "quickly"
Some of the sponsors here can supply super auto machines that also grind the beans and have auto maintenance programmed in to them, this may well suits your needs, depending on budget.
Good coffee even fantastic coffee can be had by an entry level E61 machine and a good grinder to match or even the Sunbeam cafe series espresso machine and grinder can produce great coffee in the right hands. But to be honest they all require plenty of practice and patience and depending on what you term "quick" may not be quick enough for you.
You also need to tell us your price range or budget as this will trim down the options we can advise on.
Good luck !
