I like to stay with volume mesurment since it is easier for mojority of my potentila customers.
Really? You think so?
You're saying you think people who are willing to give up a few hundred dollars for something that only has one purpose and takes skill and knowledge to operate would not be willing to give up $30 for something that constitutes part of that skill and knowledge. I don't think so. If I put myself in the shoes of your target customer, I see myself as someone who wants to learn how to do it right. This isn't something I'm just going to have sitting around in the kitchen unused, looking pretty, like most people's KitchenAid.
To me this is something an aspiring pizzamaker purchases after
they've already bought a scale but before they get serious enough to think about making their own MPO-like device. Especially if they're using pizzamaking.com as their primary guide to learning how to make pizza, which they probably are.
And what's the obligatory response on these boards every time some new kid shows up asking how to improve their [volumetric] recipe? We all say it: "You need to get a scale." And I think most of the new kids take us seriously when we say that.
So obviously I'm gonna have to disagree with you on the quoted text. Volumetric measurement is not easier; not for the majority of your potential customers and not for anyone. Volumetric measurement is only easier for people who are too lazy to try hard enough to do it right, and I really doubt that those people are your target market.
