One of our favorite culinary publications is Cook's Illustrated because they test bunches of products using a lot of the same criteria we do. Cook's Illustrated picked the Magnum Plus as being the best pepper mill on the market. This larger version of the Magnum is a favorite with restaurant folks because it has a huge capacity (read: doesn't need to be filled as often) and it holds the coarseness adjustment you choose. The manufacturers even make a holster for it so that servers can have a Magnum at hand when they present you with your salad. It stands 9" tall.
