The cheapest electric grinder worth buying for espresso.
The Smart Grinder Pro is the default recommendation for anyone who wants an electric grinder under £250 that can actually do espresso. 60 grind settings provide enough resolution to dial in most beans, the digital timed dosing is accurate enough for daily use, and the 50mm stainless steel conical burrs produce a respectable grind. It's not going to match a Eureka Specialita for consistency, and the retention is higher than single-dose grinders, but for the price it's remarkably capable. The Sage ecosystem integration means it pairs naturally with Sage machines.
Sage Bambino, Sage Bambino Plus, Sage Duo Temp Pro
You want an electric grinder but can't justify £350+ for a Eureka. The Smart Grinder Pro is the floor for acceptable electric espresso grinding. Below this, you're better off with a good hand grinder.
