For the price, hard to beat tbf.
I have a Eureka Mignon grinder and was happy to spend almost £300 on it. May be better options now but the was the single biggest element of overall espresso prep.
I think for price/performance the Sage is a good choice but depending on how into it you want to get (occasional drink versus all-consuming hobby), you’re at the lower end and may want to upgrade. FWIW I almost bought one of those too but I wanted to invest in something a bit higher end and more repairable. Just my experience, you may be very happy with the Sage.
I’m actually more keen on buying a cheaper model if they have good reviews, like what you mention. There’s a few on Amazon that seem to read well and my coffee intake isn’t at the addict level of some so could probably survive fine with something basicI bought a grinder on Amazon years ago imported from Germany, was cheap like £40 still going.
Only criticism is really loud, and getting fine adjustments on grind amount is pretty fiddly.
Edit: this one.
