I second the KitchenAid ProLine recommendation. I bought one to replace a Gaggia burr grinder that I was sick and tired of completely stripping down and reassembling — a fiddly and time-consuming process — every time it clogged up with fines to the point that it wouldn't grind any more, and have never regretted it.
Three key points in the KitchenAid's favor:
1. It is almost immune to clogging up with fines, because it is the only burr grinder I have so far found with vertical burrs, meaning ground coffee exits the grind chamber straight down instead of having to make a 90° turn to go out the side.
2. GLASS, not plastic, input and output hoppers mean no static charge build-up in the output hopper, so your grounds pour out cleanly with just a light tap on the bottom of the glass.
3. Not only does KitchenAid EXPECT you to service and adjust it, the user guide includes exact detailed instructions on how to calibrate it for a proper espresso grind, and it'll handle any grind from Turkish to French press.
(It also doesn't hurt that, like KitchenAid mixers, it's engineered to survive the apocalypse.)
