This Solis 166 can grind a perfect turkish and choke my Gaggia Baby like Popeye does Bluto.
Negative Product Points
Once adjusted (talk to your supplier, mine was set-up for espresso) the range is limited: if you want it espresso machine fine, use another for the French press, but if you usually prepare filter or vacuum coffee you can still get any espresso grind. Very limited "dust" IS present.
I had a Broan coffee grinder, a gift, seems to be a kind of quasi-burr affair. The Broan worked O.K. for my indestructible stovetop Atomic steam unit but with a pump espresso maker I needed something more. This was the solution I found that I could afford.
The Solis is a compact unit of similar size as the Broan. It is more easily cleaned and quieter, has less static problems (San Francisco is very moist year round, so you may have experiences that differ) and unlike the cheaper one it is suitible for any espresso machine.
I bought it because its burr system looked like the burrs on the classic hand grinder we wore out years ago -- a wooden box with a handle on top -- but on the Solis, the burrs were beefier and machined. If you had the energy and the time, that hand grinder would give you good turkish. The Solis does it the same way; with its gear reduction, it slowly grinds coffee into a removable "drawer."
Incidently, a new Solis model with a different footprint with an ovaloid "gallery" instead of a hemisheric hopper is coming-out as a replacement of the 166 but it is fragile...pieces pop off the gallery/hopper. This one is fairly robust.
I rate it low on the numeric only because there must be room for the tall boys with dosers and such that cost alot more
