I see where you did your comparing...

Agreed. Then you will definitely want to switch to 16F628. At 25 parts on
digikey the price drops to $2.21 each. You can buy 25 of them for the price
of Stamp Starter Kit.

The F876 and F877 are the top end of the family. The lower end of the family
(870,871,872) definitly come in lower in price than the 16F84A.

And the programmer is simpler....
