I should state up front I know nothing about the certification process. I agree, there is a lot of benefit to having a working system, even if it means barrier to entry is high. It sounds from your comment like most of the cost is due to the regulatory structure, and not from the testing end, is that right? I'd love to see a cost breakdown of doing a certification. Someone else quoted $250-500/hr for testing. What goes in to that? Testing equipment? Facility build out? Testing technicians?
