I also just ordered a Niche, after becoming quite impressed with the Lelit grinders, the Eureka Mignon series and their price point, I almost went for it. But the moment I saw that there was an available for Indiegogo I placed 1 unit.
I'm doing this also based on the advise of the members here to park my large budget in the grinder alone, the unfortunate thing is that it only comes in March so I have to hold all my beans purchases until then - live with my current Nespresso.
It is also a notable thing to state, that I went different in this style of purchase, I placed a purchase first on the grinder - without an espresso machine. Was in Taka today, fell in love with the Gaggia, then I saw the Lelit Bianca, and I felt that its such a beauty, then again, I likely won't have the luxury of time to learn and do barista for the family, when the office opens up.
So, espresso machines I'm leaving an open decision until mid February comes around. That being the case what was your first mid-range prosumer machine?
