I was afraid my mill (a Wondermill) would be a large, expensive folly....and I've used it every week for a dozen years now, and would rather have it than any other kitchen implement. I do about 5 pounds at a time, for 4 loaves of sourdough (I make 2 right away, the dough for the other two sits in the fridge to be made about 3 and 6 days later). It's cheaper than flour, but most of all it's much better/fresher, and also much more convenient (at the time I didn't have a car, and who wants to lug 5 lbs. of flour home in a grocery bag every week with all their other groceries?). I get 4 or 5 50-pound bags at a time, from a WA producer or from Azure, and then never have to worry about running out.
