Part of the problem with mass market products (electronic or otherwise) is the multitude of tradeoffs that designers need to make. Anyone whose requirements are very different from the median is going to have to do a good bit of shopping around, and probably some mix-and-match, to get what they want. And this is not going to change unless you can convince some manufacturer that you represent a large and stable enough niche market for them to make money from.
