While most people believe that an espresso machine is quite standard it is actually highly incorrect. If you are concerned with making absolutely certain you get a great machine, you need to understand the differences between a home model and an espresso machine that is intended for commercial usage. Most homes are able to use a home model quite easily. However, if you have an extremely busy household it might be worth the expense to purchase a commercial model. Look over all of the information for each model before making an actual purchase to be certain you get what you need.
