The Ditting KR805/Mahlkonig Tanzania/Marco Uber Grinder is apparently the best, and who am I to argue, I've used them and get a very complex taste on the V60, woodneck and french press, tastes that are exactly on the roasters description. By far my favourite for pour over. Perfect for the single dose, with a little tapping of the lid and the bag holder handle. 15g in 15g out.
The Malykee Coffee Grinder - All I can say is wow, pretty.
Baratza/Mahlkonig home grinders - These charts say it all, I think they may have got their 585 and 586 mixed up though.
THE Mahlkonig K30 - Is my choice for an espresso grinder.
Robur E - Also called the beast.
Hario Hand Mill - Hook it up with a drill and wham bam thank you ma'am.
Versilab - Very very impressive single dose grinder
Let's not forget the Ceado E37 - What a nice machine - Looks like a small neck, doubt much would get stuck in there.
This hand held beast - probably the best hand grinder out there.
I have seen a modified Kitchenaid Vertical Burr grinder with mazzer burrs, it looked like an improvement.
That's all for now folks!
