   Yes John, That is exactly what I mean

   I would love to do this but unfortunatley I am only the manufacturer of this   
   device and make but a few pennies from it.   
   The middle man makes a fair wack and only complains about cost - the usual   
   scenario!   
   The circuit is kept to its bare-bones.
