My buddy and I are considering building a mod for the Rep-Rap that would print quietly (no more music), have higher resolution, and be tolerant to table bumps. We think we can also double the accuracy of positioning the print head.

The design uses expensive motors and a custom control board. Would people be willing to spend $1000 to replace their NEMA 17 stepper motors and control board in order to get a quiet 3D printer that prints more accurately and can handle being bumped?
