I guess it might be controversial, but I actually like the design of this machine. Apart from the ethical aspect, I would consider buying one. That said, I think it would be great with a commercial option for those who want to have a MIDIBox SID but don't got what it takes to build one.
Personally, I think I am able to assemble my MB-6582. At least I hope so, as I've recently found myself ordering parts for one. However, was there a pre-built option, I would have bought it, as my main goal for now is to make music. Part hunting and soldering is fun too, but that I can save for a project where the final product is less interesting and the build process is the point.
So, T.K., my suggestion is that you create a fair commercial license allowing companies to build and sell machines based on your product, paying you a license fee for each sold machine. Still, of course, keeping the noncommercial DIY license option for those who love the sound of tin melting.
Sorry if this is already discussed. I'm new to the MIDIBox community.
