Customer comfort level cannot be overstated, that's for sure! I think that more familiarity with the area of interest invests a higher degree of comfort to any type of purchase.
Take
my bicycle purchase, for example. I've been bike commuting for 20 yrs, & I've purchased and built quite a few bikes over the years. I've also developed very specific opinions about what features belong in the product. As such, I had very few reservations about buying a craftsman-created product (a hand-made frame & fork) using non-mainstream design & materials (randonneur features, silver-brazed, lugged, steel tubing) to provide the precisely-tuned results I couldn't get from a production vendor. Other folks will spend more money buying from a production bike maker simply because they're more comfortable with a mainstream product.
It's no different with houses, cars, furniture or fly rods. Or espresso eqpt. There are unknowns when dealing with any craftsman builder. But there are also advantages that you'll never experience with production-made items.
I view Versalab the same way. Do you want the gentlest & most direct path from burr to basket? Then you'll have a lot more comfort with Versalab's design if you learn what it takes to get there, & understand why production vendors don't want to invest in the tooling to create it. The resultant M3 design is definitely not mainstream, but the advantages of dual burrsets & not cramming every grind thru a 1/2" hole is phenomenal in the flavors created in the cup. You won't get "a 5 year warranty," but they will personally support your grinder for as long as you own it!
It's kinda overkill for the home user (not that that means anything to folks here

), but
here's a view of Versalab's optimum operating setup. When you combine the grinder, hoppers & press, you can see how they're really designing for the commercial environment. They even 'splain some of the M3's advantages on their
In the Coffee Shop web page. Surprisingly, most cafe owners (that I've talked with) haven't thought about any of these things!
