You guys and your fancy kit airplanes...
$400 is more like 2% for some of us.

$400 or a proper maintenance schedule will net the same reliability.

I wouldn't pay $400 for headsets, either;  but, that isn't the point.  
The point is that $400 IS a lot of money, and that is a separate 
question that whether it is justified or not. 

Planes get expensive in the same way they get heavy...one pound at a 
time...which would be such a profound statement if we were British.  
System after expensive system is piled on, justified in each case by an 
obscure what-happens-if scenario.  Meanwhile, where we started gives us 
more performance than the typical 152 most of us did our primary 
training in.  I believe I've read that the training fleet is one of the 
safest components of the GA fleet.  IMNSHO, over the lifetime of the 
coils, the $400 would be better spend on an extra couple hours of 
recurrency training with a good instructor.
