2. A lever or piston espresso machine is a great option if you don't mind the work. Often, they require a bit of physical exertion to create enough pressure. Overall though, the quality of the espresso is superb. Also, they are quiet and require very little maintenance.
3. The quickest way to get espresso at home is with a steam-powered espresso machine. However, creating enough steam for quality espresso is sometimes problematic.
