The reason those boards you buy are cheap is theres a boatload of people who pay for them. Need quite a bit of volume to get a custom, high-performance ASIC and board down to a few hundred. The problem is on the demand side. The suppliers would have to come up with millions of dollars for development and advertising then risk losing most of it. Most that do go bankrupt or get acquired after they fail (esp in FPGA or accelerator space).
