Query: The knob is the weak link

I've had two of these units and they have both suffered from broken knobs. Looking around the 'net, I've see others complain of this flaw as well. The replacement is twenty bucks plus shipping, so figure on ordering one of these as well. As long as the knob holds up the pot itself is nice and brews a great, hot cup of coffee.
