Agreed. I verified today the availability of production quantities of 
the AT90PWM series chips, and these seem to have sufficient resources to 
do what I need. I'm still wrapping my head around the PWM peripheral, 
but so far it looks pretty good. So, at less than $5, for these, yes, 
$20 is a lot.
