Why buy when you can make?
What I love the most about the SBC and 3D printing community is how hard they go in on the mentality of "don't buy, build." If they see a product they want but it's too expensive, the cogs start turning within their heads. Give them a few days and a GitHub page, and they'll find a way to achieve the same result with a fraction of the price, with open-source plans and code, and somehow fix people's problems with the paid product.
