I forgot to mention: I use my Rocky for drip, press and espresso. The easy adjustability of grinding for all three methods is a feature of the Rocky in my view. I probably grind a little less than a pound per week for drip and press and about six shots of espresso per week.
Over on Home Barista, the Rocky now gets relatively poor marks as an espresso-only grinder against the current competition. If I was running a cafe, or was pulling dozens or hundreds of shots per day, grinding only for espresso, I would probably get a big Mazzer grinder as well. I would imagine that a big Mazzer grinder for home use is over-kill, but who am I to judge?
