Have a Black & Decker, cost $14. We make 2 or 3 pots a day, have had it for over 2 years and it works fine. Usually we end up breaking the carafe before the coffeemaker dies and it's only a couple of bucks more to get a new coffee maker than to replace just the carafe.
We have friends who have a $100 Bunn, and their coffee tastes no different than ours.
