We love our build in Coffee Machine.  We've had it between 2 and 3 years, and it makes probably 2-6 drinks a day.  The only maintenance needed was some grounds needed to be cleaned out from a clog (I think we used beans that were too oily).  Other than that regular maintenance is all the upkeep needed.  By far our favorite kitchen appliance!  Wish the milk could be refridgerated and not placed in a cannister each time.
