Mignon Zero Brew

I'd go for a Eureka Zero, I love the grind by weight (GBW) workflow and am getting very consistent shots

I’m pretty sure I got my rancilio Silvia and eureka zero for around that much

I agree. I also had an Eureka, the Zero, and it was the most silent I had so far. And the retention doesn't improve with an inclined base. I 3d printed one and tested. Which for me means that Oro is a bit overpriced for the advantages offered when compared to Zero. But probably the grinders with DC motors can be even quieter like the E55. But I don't have experience with any so far.

Avoid the fellow grinders - there are much better ones around. Baratza encore ESP, or, something like a eureka zero , both will be better than the opus *NB the ode is not espresso capable.*

My Eureka Zero has served me pretty well so far too. Basically a single dose version of Specialita

Eureka zero and big grinder setting dial from aro. Easy to switch back and forth with new dial, built like a tank, relatively silent.

I would add Timemore 064s to your list if you can get it during one of Amazon's frequent 20% off sales. It's great for all brew methods and all roast levels. If you go for the Eureka Zero, get the 65AP version. The original 55mm version is better for darker roast espresso. The 65AP will be be better for all roast levels and also for drip. https://preview.redd.it/cumdgxdk75lg1.jpeg?width=664&format=pjpg&auto=webp&s=3d9468a0033cf5b4401b363c6ee402a11700efbe
