I'm wondering why the project terms include a prohibition on selling parts kits. I'd like to build this project, but I can't buy most of the parts in single units, as they are listed in the parts list. I have to buy 5 of this or 50 of that, then pay many separate shipping charges, which means in the end the cost is much higher. Buying a parts kit would make this project more affordable and easier for those who don't already maintain a large stock of components. --Michael
