I was content with my SB EM0480 while I had it - I hadn't used any other grinder. Upgrading from the SB EM0480 to the Breville Smart Grinder was like a dream for me. It is faster, quieter, cleaner, grinds finer and the result in the cup made the purchase a no-brainer, I only wish I had done it sooner. I reckon the Smart Grinder is superb value for money.
I have a SJ Electronic on order and am curious how much more of a difference I will notice. Anyone have both that could shed some light? Any SJ users that can tell me how fast it will grind? Anyone tried the Duranium burrs?
