Not to divert the thread here but for many a manual grinders claim to fame vs a similar electric grinder was threefold, the ability to get into large conical burr grinder family at a lower cost, low grind retention and the small footprint. I only mention this because I read here how much easier the M68 is to grind vs the Pharos as a selling point. What's even easier, faster and less frustrating is a motor assisted grinder.
With the introduction of the soon to be delivered electric Niche Zero grinder with 63mm conical burrs, low retention, lower cost and similar footprint of the M68, the purchase validation of a large expensive manual grinder becomes moot. Some may argue the beauty of a fully mechanical grinder and some may contend the ability to grind without electricity but I doubt the M68 would be considered a portable grinder based on its size and mass. Curious to the purchase rationalization of an expensive manual (main) grinder vs similar electric grinders either in the market or soon to be.
After all not an over diversion, as it does involve the M68.
Between order and chaos there is espresso.
