Perfex Pepper Mill

I concur. I received my Perfex as a wedding present, 21 years ago last month, and it's been used for nearly every meal I've cooked since. I own probably half a dozen peppermills, which I use for different blends, but this one's the kitchen workhorse for black pepper. It's easy to fill, easy to adjust, durable and compact.
However, if I were buying another peppermill just for fun, I'd get the [url=http://tinyurl.com/fewx9]Trudeau Graviti:

I got to play with one at this year's Housewares Show and it was a hoot. You just flip it over and it starts grinding by itself. I don't imagine you'd get decades of use out of it, but it's relatively cheap.
