Query: dusty and messy

I'm in search of the perfect grinder, of course. As a decades-old coffee drinker, I've tried several. I was reasonably impressed with Starbucks' Barista-brand burr grinder. It got all the grind settings right, even for espresso, but after each use a small pile of grounds wound up on the counter. So I tried this Cuisinart, since I have the company's coffee maker and the price was right. However, I have a couple of complaints: (1) the ground coffee must pass through a very narrow chute into the container, so the chute clogs easily; and (2) there was so much static friction from the grinding process (or whatever) that excessive ground coffee would attach to the container's sides. After each use, I had to spend several minutes cleaning up.Now, onto the Kitchen Aid.
