I've had it on my list to build one for a couple of years. The EGOs cost about $35; the parts for the box are probably $10-20. There's a schematic under http://efi332.eng.ohio-state.edu/diy_efi/projects/projects.html that looks pretty straightforward. My impression of the EGO output is that the commercial units that give you 30 LEDs worth of resolution are mostly overkill. The peak in the middle of the EGO's range is *very* sharp, and a 10-segment LED display should be plenty.
