Low cost microcontrolling

I had a terrible issue at work today. We certainly have to give up from a windows controlled device, depending on time critical software to use a cheap and easy to find microcontroller.
Making a couple of phone calls to local electronics shops, draws me to one single option. Microchip's PIC 16F family.
So, let's go to PIC world: http://www.grennan.com/picprog/ (Programming the PIC16F84 with LINUX) The PIC16F84 is easily found at any electronics shops in my town. It costs around R$ 15,00 (fifteen reais), local brazilian currency, which is around US$ 8.45.
