I have the predecessor of the encore (basically updated to an encore), and it's a great grinder. I know a couple of people with the ESP, and they seem to like it as well. The only downside is the grind adjustment ring and burr carrier are plastic so it can technically get a little wobbly over time. Those parts are easily replaceable, though.
The sette, I think is mostly just for espresso? I know you can also buy the parts to turn it into the sette 270, too, so that might be a good way to go.
