Cooks Illustrated held the Unicorn Magnum up as their top rated pepper mill for a long time. I've given a few as gifts, some of which I also used, but was never giddy enough over it to buy one for myself. Recently though, Cole & Mason Derwent displaced the Unicorn in the top spot. They were sold out nearly everywhere after the review came out. I bought one when they became available and I am quite pleased. It has six grind settings from fine to very coarse, and the settings lock such that it's virtually impossible to change accidentally. It has a steel mechanism and a brushed aluminum and clear acrylic body that lets you to see the peppercorns. It solves the issues I had with the Unicorn: pain in the arse to refill, can't see when supply is low, grease and fingerprints on black plastic, and it's plastic, looks plastic, feels plastic. The U-Magnum is also top heavy will tip easily if you shake the table. The Derwent is quite stable - actually hard to knock over - and has a pleasing form. It looks like a pepper mill and feels right when you use it. It also costs less - $37 and free shipping on Amazon.
Now I need to find some great peppercorns. The CI top rated tellicherry peppers are Kalustyan's but they're sold in 2.5 oz quantity and cost $7/oz with shipping. Does anyone know where to source comparable quality in bulk (pound or half pound)? My local gourmet shop did not have anything other than supermarket brands, which means low quality at high cost. I'm betting that someone is selling quality in bulk/generic packaging but there's no way to know about quality without a recommendation.
