I have a wilfa svart for pour over. Happy enough with that, i have espresso burrs in my major, if ssp did brew specific for the major id of happily spent another 250 on a second major, and get those. Sadly ssp seem to have focused on 64mm for three different burr types.
The mignons that ive had have all been tbe £350 or less, 50 and 55mm versions and they have been ok. I really disliked my eureka 65mm, wasnt a good grinder. As for the sd mignon it looks like they have tried to make do rather than re invent, there not the best for switching between espresso and brew either.
