Home machines like the Saeco use a basket with a restrictor-jet on it that sprays out the coffee and induces a foam that looks like regular crema. On such machines, even normal home grinder will work fine. The resulting beverage does not have the density of espresso, but if properly made with fresh beans, can taste like good strong coffee. Home super automatc machines work on the same principle and yield the same results.
Capsule machines like the Nespresso or Illy Iper do real espresso extraction, but use lower grade and stale coffees at much higher per serving costs. These taste like mediocre Italian espresso and are the most convenient way to make shots (if you go this route, do not use the old ESE pods, since they do not work as well).
If you want real espresso and cappas for the home made from good fresh coffee, you are looking at a good deal more money. A minimum set up would be the superb Baratza Vario grinder, and a low end heat exchanger machine like the NS Oscar or one of the new small boiler plus steamer thermoblock machines like the Breville or Quickmill. You are looking at around $1500 for the budget on this, plus a few months learning how to become a competent barista.
