At first, I think you need to make it clear which kind of coffee maker you would like to choose.
There are mainly 4 kinds of coffee makers, namely, Automatic drip coffee maker, Percolator, French press and Espresso coffee machine. There are many reviews for coffee makers, and I could give you a short introduction of the main coffee makers.
Automatic Drip Coffee Machine is much easy to use, and could give you a fast coffee. There are many kinds of coffee makers. And there are many add-on features for you to choose which makes the usage much more convenient. Espresso machine is a relatively high class brewer, it brings much better flavor at the same time of higher cost. While some people like espresso very much. As to French Press coffee maker, it is a very classic way to brew coffee, and the water temperaand brewing time could be totally controled by you. It does not support electricity-auto, you need to do it by hands.
