Eureka - Mignon Brew Pro

The Eureka Mignon series will grind to the 190-195 micron range depending on which model.

Yes, I think they are great. Much less retention than the Mignon we originally bought & then returned. Easy to adjust, reliable. We use it for decaf, V60 & filter in a small cafe.

Two grinders is better than one if you switch brew methods. Ode + Mignon = better filter + no dial-in pain. Single “do-it-all” grinders always compromise.

Have owned all the grinders on your list, at one point or another. Agree that Duo might be your best bet. Ability to play with other 83mm burrs is a good hedge against future curiosity. Recommend getting second (filter) burr option, because having the extra carrier for fast(ish) swaps is nice. Cannot recommend the Eurekas. Good build, very pretty, but burrs are proprietary and the grind chamber/chute design is antediluvian. Fine for hopper base on-demand grinding, but crap for single dosing. Even with the mods (tilted base, bellows), retention is terrible. Eureka’s attempts at single-dosing focused grinders are not honest efforts. Just a new model name and superficial accessories. And their new dial is just…stupid. Still not enough ratio to overcome the thread lash in their adjustment screw. The rev counter is nice enough, but a big dial like [this](https://www.amazon.com/ARO-EspressoTM-Eureka-Mignon-Adjustments/dp/B0CLCB8VQ6/ref=asc_df_B0CLCB8VQ6) is much more effective (and not stupid looking, imho) Libra portafilter contact sensor was unreliable. I heard they fixed it, but I had given up already and moved on. When it worked, it was…ok. Weight accuracy wasn’t bad, but irrelevant because it was a hot mess of sprayed grounds. RDT absolutely necessary in my environment (20-50%RH over the year), but the extra moisture caused caking/clogging in the chute. From a taste perspective…it’s ok. Blendy, decent body, not a lot of clarity. Little unkempt and harsh. Good in milk drinks. Niches — good workflow, probably among the best, even compared against titan grinders at 5x the price. Personally, not a fan of Mazzer burrs. Harsh and bitter finish. The Zero doesn’t have any options for their 63mm conical, so you’re kinda stuck. The stock Duo espresso burr was, to me, a cleaner version of Zero profile. Other options: Mazzer Philos. The grinder itself is a bit pricey, and rumor has it that the i200D and 189D burrs are big improvements over Mazzer traditional flavor profile — but it’s a good platform for 64mm burr space, where you are spoilt for choice and the burrs are cheaper than 83mm. Hope that helps

Eureka Mignon it is. You can buy a third-party steps dial (Etsy should have it) that would help you go back and forth. 

Second a eureka mignon - Italians make good motors

Ja mám už roky delonghi dedica s vlastným sitkom a pákou (neviem, ako sa to po slovensky správne volá) a eureka mignon mlynček. Do 500€ by si sa mal vojsť.

Eureka Mignon, Set time, grind size once. Forever after just press the beaker up againșt the grinder to start grinding so really I would call that half a button. It's consistent, can do just about any coffee and precise. It's built like a tank, lasts like a tank, weighs like a tank all while optically oozing the sleek but rugged luxury vibes of a chrome G-Wagon for your kitchen. Its an expensive, delightfully over-engineered flex of a product, but then this is what this community is all about.

I have the Ode and a Eureka Mignon. The Eureka is strictly for espresso, while the Ode covers any non-espresso preparation.

Just get two grinders. Funnily the Eurekas are considered very good for dark roasts so my recommendation would be to keep that but that doesn’t seem to be an option.   You could change the burrs though. After 10 years they might be at the end of their life. Het a set that’d work for dark roasts and use the remaining 550-600 bucks to get a decent light roast grinder. The budget is tough though. You would need a bit more if you would want to have a good improvement over you current setup.
