Don't waste your money. Drop $250 on ebay for a used Mazzer, it doesn't matter what type you get (mini, Jolly, or Super Jolly). Take the burrs out and replace them. Now you will have the best espresso grinder.
For drip coffee, look for a Grindmaster, Bunn, Fetco, or Ditting bulk grinder. They are all pretty much of the same design. Granted I know most people would prefer the Ditting, but that's not the point. Look for a 1 pound coffee grinder. Replace the burrs in it as well.
If you are using either machine for home use and you have replaced the burrs. The machine will out live your life expectancy for grinding purposes!
