At least with coffee grinders you can measure the distribution of particle sizes to see that cheaper grinders are producing something quantitatively different as output, and use blind tests to see if you care. $1650 might still be a bit much, but the way you grind coffee does have a surprising impact on how it tastes.

I’m not a coffee “enthusiast” but we have a grinder at home, and I’m definitely not getting the same coffee as I did in the office when I used their grinders.
