I noticed that Dikigey has all of the parts ...
Atmel AT90S4433 microcontrollers are $6.45
http://www.digikey.com/scripts/us/dksus.dll?Detail?Ref=73899&Row=83392
INA114 instrumentation amps are $6.82
http://www.digikey.com/scripts/us/dksus.dll?Detail?Ref=74183&Row=121477
TLC277 operational amps are $1.85
http://www.digikey.com/scripts/us/dksus.dll?Detail?Ref=74248&Row=27362
Atmel Tiny AVR starter kit is $79

But a schematic for the programming cable is here, so I assume the kit
isn't needed.

The Atmel DevTools are free

PCBexpress accepts Eagle format files and does low volume orders

I think we should order some boards and test this ModularEEG
and start writing some FFT and IIR/FIR routines ....
