I really liked that idea, but at the time when I was looking for a new scale none of the mechanical ones I encountered had the combination of a resolution of 1g or less (I also use it to weigh beans for espresso) and also able to weigh up to a couple of kg. Though maybe I just didn't look hard enough.
