Well, thanks for the info. I'll give them a call. I suspect that most of the dollars are in the servos and hardware and not in the panel heads (just buttons and switches)
A little research on the Trio web site will reveal that the cost of the servo is slightly less than half the cost of the entire system. The control heads are much more than just switches and buttons since they include the processors, display, AHRS sensor circuit boards, pitot/static sensors and proprietary software...and probably some more stuff.
