I hadn't heard of that particular model either. A fast search led to lots of consumer reviews on amazon.com. Their reviews suffer from shills (marketing agents posing as consumers), but the complaints are often valid. This one caught my attention:

Regardless of the setting you use, you will get half coffee powder and half coarse grounds. In addition, the feature that is intended to allow you to control the amount of grounds you make with a switch on the top ... does not work. Be prepared to grind more than you need, and then measure the grounds (somehow avoiding the powder) yourself.

Don't sweat it too much. In my opinion, **all** grinders suck when it comes to shot by shot usability, either at home or in a business; dosers and doserless just suck in different ways. The main thing is to get a grinder that grinds really well, and secondarily, is relatively durable and quiet.

The Cunill grinds very well, is durable and relatively quiet. It also comes in both versions, read all the opinions, then follow your instinct, pick whichever looks cooler, or flip a coin -- there isn't all that much riding on this decision.
