I'm over pre-ground supermarket coffee. But I don't drink that much that I can justify the expense of a decent electric grinder. The Hario hand grinders seem to get pretty good reviews, some saying they do a better job than a lot of electric ones. You can pick up the mini mill for less than $40 on fleabay... Anyone got one? The Mini Mill or Skerton? How long does it take to grind a dose?
