Atmel AVR microcontrollers are < $10 from distributors like Digikey (and 
Digikey usually has high prices). They're very slick and VERY FAST. You can 
do 12 MIPS with one of their chips.

Of course you'd need to spend some time learning their instruction 
sets/learning how to code in C for them. There is a C compiler in the ports 
named avr-gcc to do just that.

As for programmers, you can program these chips with a simple homebrew cable 
that plugs into your parallel port.

Is that cheap enough?
