When you choose a coffee maker try to get a reliable coffee maker and decide if you want a single cup coffee maker or a 6 cup coffee maker or a 12 cup coffee maker.
Of course if you're in an office setting you may want a larger coffee maker to provide the workers in the office with plenty of coffee.
At home I have a Mr Coffee coffee maker that is both cheap and reliable and makes the coffee I need.
Some people prefer single serve coffee makers while other people want more than a cup of coffee made at a time.
