um.. how many people in the office? and how much use daily? Those would be a first consideration, I suppose. As for matters of taste vs. practicality, simple is better on both fronts probably, unless you are getting an industrial brewer. There will be others with much more substantive suggestions, I think, but I've thrown out a number of coffee makers (and at home now only use a press, because I can). In the office I always went for good beans, newly ground, with a simple machine, and got good results. For a few servings of coffee on demand, I should think there are many machines that would fit the bill.
