My objection to the Rocky isn't so much it's grind quality. For what one of these costs new, one could buy a much better grinder (Cunill Tranquilo) and have a hundred or so left over.
Hmm ... so you're saying the Tranquilo has a better grind than the Rocky? Is the Baratza Maestro any good?
The Tranquilo is almost identical to the Mazzer Mini as far as burr size, motor power, weight & size is concerned. It's far superior to the rocky & Gaggia MDF (Rocky's competition).
I've not played with a Maestro in a few years - but haven't heard many really good things about them.
