There is a lot more to consider in production costs than just buying parts and putting them together. Just because a machine may be "smaller" does not always mean "cheaper" production. Things like electronic boards stay the same price no matter how big or small a machine. The only two things that drop the costs are buying in bulk or make them yourselves. That brings up another issue. To fill an order of 7,000 machines a manufacturer will need help. That also drives up the cost of production. Unless you spend 5 years and do not sell another machine. Kickstarter is a great place to introduce a product. But those who use it must understand that it isn't a business.
