but i'm with you on the grinder. i have the sette 30 and it's fast and consistent, with little waste. i primarily do single serving grinds for brewed coffee with it. the gearbox broke but baratza sent me a new gearbox for free (i believe there was a manufacturing defect in the early models). i got the 30 (the number of grind settings) because i wanted it primarily for pour over rather than espresso. the great thing is that the grind adjustment mechanism can be upgraded (along with the controller faceplate to get presets) and effectively turns the 30 into the 270, which i may do if i ever decide to get an espresso machine.
edit: i also got the courser burr, taking the grind size up to roughly a medium grind, which is perfect for pour over. the included burr is better suited to the fine grind needed for espresso.
