Coffee grinder

I want to buy a new coffee grinder. I want the kind that allows you to set the coarseness/fineness of the grind. I would also like it if I can set the amount of coffee to be ground. I have a perfectly good coffee grinder from Braun, but it is the kind with spinning blades and it is tedious to grind coffee with it. I want to use it for grinding spices.

Does anyone have experience with this kind of coffee grinder? Does anyone have any recommendations for a good brand? I would get the Braun, but I can't preset the quantity to be ground. Does anyone know the cheapest place to buy a good one? They had expensive ones at Deco Decouvert. They had less expensive ones at Centre du Rasoir! But, that's all the places I've checked so far.
