the 8051s that I am using is $2 each. And I am trying to push it down to $1 each or below $1.

I will properly need 300 to 500 at the beginning then than more to come.

when u said Cygnal's 8051F305 could be found at lesser than $1, in large quantity. How large would be consider to be large?

Thanks for all your information, they are very usefull to me.
