I have a Whisper Mill electric. It's great for flour but I dont think it can do nuts or anything more moist than grains. A word of caution though - I recently was grinding up a lot of flour and overfilled the tub the flour goes into, so it backed up and then next few times I used it, flour would come out the sides and it was VERY MESSY! But my husband took it apart, pushed the foam back where it was supposed to be and it's fine again. I'm just not to overfill it again, my husband says! :^)
It's a whisper mill, made to be quiet but I think it's still loud (as in, I wouldn't use it if a baby just went down for a nap) It's very quick tho!! and nice to have finely ground wheat flour!
Oh and I've got a yummy recipe for a poured whole wheat bread (no kneading). If you're interested, email me!
