If airframe designer had already done all the work of designing and verifying the installation, then sold you a set of plans saying "do it this way", would that change the equation? It just seems that most of the time and expense that I've seen from people on this list can be attributed to the growing pains of any new design. The people that choose to follow the conservative designs of successful installations seem to have a much easier and cheaper go of it.
