Could this be another possible controller. Certainly the programming language will have a shorter learning curve.

Possibly but I'll bet it is not $90 :)

True, it's $195 in 100 qty. But it is built to industrial standards, in addition to the simplified programming, has common up to date porting, could be updated by user without having a dergee in computer science, just a few thoughts. Minimum cost isn't always the only criteria for a given solution. Is the $90 you refer to the price of the USBiDAQ? If so doesn't the complete system require another host computer resident in the installation on board the aircraft? If so, then you now have price parity. I have seen the inside of the USBiDAQ, and I can't quite say for sure if the production standards are going to stand up to a flying aircraft.
I dunno, just thought I'd toss it out there.

It is also missing the counter timer and PWM.
It won't store data and it won't drive a glass cockpit.
