Thanks for the info - I will put this into consideration.

Approach thus-far has been to hybrid both controllers, as I do lack the programming, micro-controller / PIC expertise required for that. (though with guidance I'm able to do it, as I have done so before)

Oh yes - for everyone - the project is not dead - been busy month - serious family related things dealing with. Will resume once life returns to "normal".
