I'm building my electronic based on RAMPS, but for the Arduino Uno. I suppose it can work on the Duemilanove as well.
My idea is to make it into small modules so it can fit with different micro-controllers or add modules to add more functionality (heat bed, dual extruder, lcd screen, ...). I like the idea of a diy solution and I also try to make it as cheap and accessible as possible.
Look at it, if your interested, i'll add more info about it.
