I have a KA blender. Love it! (Loved it, I need to replace the cannister DD2 smashed ) But it is a great blender, aside from the child destruction, it has needed the spinning thingo in the bottom replaced once ($7) but I don't think they make the new models the same way.
Mine is 5years old and in perfect health, motorwise. It is the only KA appliance that has lasted the distance! LOL
