This is by far the most affordable and portable coffee grinder that can yield consistent espresso grind.
I’ve been a fan of the Breville Smart Grinder for more than two years and I’ve been rather happy with it. For home use it’s perfect. Being my primary grinder, especially in these times of pandemic, I do get paranoid with the wear and tear. It’s an appliance, for one thing so the parts are proprietary. Don’t get me wrong — the only issues I have had with it was clumping due to the heated burrs. These times of pandemic however — I can live without an espresso machine but not a grinder. Freshly ground beans are way more important than the coffee method.
