Best pro-level grinder in this price range (get the doserless, not the doser, model--even though doser looks better)
Positive Product Points
Price is right for pro results, but they should redesign chute and dial to match the solid looks of the rest of the machine and Silvia
Negative Product Points
Chute and dial/grind selector look a bit cheap/plastic compared to rest of machine
After being convinced (from all the reviews here and elsewhere) that my trusty little Krups grinder just wouldn't produce decent ground espresso for my new Silvia, I decided to invest in a more serious machine. I looked at the Mini Mazzer and thought it looked impressive but too bulky of a contraption; the Solis Maestro looked too cheap and had bad reviews. So it came down to Rocky doserless, which I figured would also look good next to Silvia.
After unpacking and setting up (adjusting the dial/selector as instructed to about 6 or 7 marks beyond zero), I put some freshly roasted beans in the hopper and Rocky produced fine powdery coffee that collected in the portafilter in soft mounds. Tamping with a weighty Reg Barber tamper and a little twist packed it down nicely at the line, and then it was up to Miss Silvia to make espresso--which she did very well: lovely, rich espresso with a nice, thick pool of crema on top. I haven't experimented with changing dial beyond 6-7 marks beyond zero, as it seems perfect right now. I know I could use Rocky for drip coffee beans too, but I may keep the Krups for that.
1st-line had a package deal with Silvia ($50 discount off Rocky's $285 list price), so I ordered them together. I also went with 1st-line because they seem to offer good Rancilio service should anything ever need to be repaired.
