I had the drip type and the press type, ala the Keithster and the Tim Horton type (every morning - $1.50) and was happy with all of them. The Keurig was a convience that turned on at 4:45 am and made a coffee in 1 minute flat the same every time. Great at household gatherings with dozens of flavours.
Mine had the "descale" sign flashing but that wasn't the problem. I've included a link for those interested explaining how to repair along with pictures of the affected solenoid and motor consequence.
