Totally agree with Hasi here. I run a Eureka Olympus 75 as my main grinder for our current 'house' blend. I then also use a EK43 to run anything else, i.e decaf, other blends, singles & also to grind peoples bagged coffee. The Niche would work well as a 2nd grinder, but you'd struggle to grind coffee for bagged coffee

Please excuse my lack of knowledge, but why use the EK43 for smaller volumes? I'd have thought it would have been the other way around - is it a retention/dosing thing, or just the cost of the burrs in the Mahlkonig?

Well like the Niche, you have to weigh in the dose. So this takes a while, so in a busy cafe when people 'just want a coffee' it would be way too slow and I just run the main fast grinder. It makes a handy 2nd grinder as it can do anything else. (you could always pre-grind a large number of small containers from the Ek, but this is very labour intensive!)

I thought the EK43 had a hopper like most other grinders - wasn't it designed to be used in a commercial environment?

it does, but it has no mech to stop the coffee. So what you put in is what comes out. You have to weigh each shot you put in. This takes time. The Eureka will stop grinding after a certain time (i.e. 7secs) so it can measure the dose, so this makes it faster.
