Klute - only basic concepts for NPPL instructors have been considered; there is no definite agreement amongst the NPPLSC yet for their appointment.
That said, the experience level and FIC required for NPPL FIs would probably not be that much less than that for JAR/FCL FIs.
The fact that 'others have paid more to be FIs' is not really a valid argument for refuting the concept of what is really no more than returning to the 'old' PPL/FI of not that log ago! However, your point of view is known to the NPPLSC as it has been expressed by others previously.
