There are several things to consider when choosing a coffee machine to buy. These include price, features, type of coffee brewed, capacity, amount of coffee produced, quality of coffee, maintenance cost, and machine size. If one cup of coffee is enough to get you started, then a one or two-cup drip model will do for you. If you need more than one cup, you can opt for the automatic or the specialty machines like the French press types that produce 10 to 12 cups at a time.
