Price. Something that can also roast a pound at a time that has actual control over what you're doing is in the $2k plus range. Maybe that is changing now with some of the Ali express roasters mentioned

Hey folks....Ross has a 3-D printed wrench he uses in the shop. He's offered to send me one. Will report back. And a big shout out to Ross

Loved that your reply on the fs link is in German . Since it is closed I assume you bought the MC6? What are the odds an almost brand new grinder came available in your country with extras and correct power configuration? Sometimes the stars are aligned

Or it's that new cutting edge coffee substitute made from baked beans?

FYI for Canadians: the pre-order is now live at EightOunce in Calgary. $499CAD (same price as the Ratio 6). No free coffee, but a very good USD:CAD exchange rate and about $10 in points off a future purchase from EightOunce (if you sign up to EightOunce's loyalty program). {link}

Hi Patsy. I don't have arthritis but have mentioned having similar issues with the cap. I think a one inch "lever" screwed unto the timber part of the knob would help. Something like a small stainless steel knob should give you the leverage required. {link}

Huge in what way, the price, complexity or something else?

This is why I quit roasting when my behmor broke. I wanted to upgrade but the jump to the next level is huge

Wow, very interesting!!
