Geistware: DA estimates it will be between 400 and 500 bones.

Vatechguy: In principle, yes one rx will be going for the ride as long as there is no failure. If there is a failure, it will be invaluable.

Blowngo: Technically, yes - however if I understand the DPSI correctly, it is a monitor and a switch. Failure of the device would mean you lose redundancy, not the airplane. Loss of the airplane would require a dual device failure. The implied risk vs. the benefit makes it worthwhile.
