I know there are a number of espresso freaks around here, so I call on you. I really like espresso and I want to start making it at home. Where should I start on a machine and grinder? I'm assuming a semi-auto is way to go? Are the fully automatic ones any good or are they the equivalent of a faster backwards Dogma with EPS and a pie plate? It seems in the semi-auto realm there is a wide range in machines as far as maintenance and convenience go. I don't mind spending the dough for decent stuff, within reason. Thank you!
