CNCfusion is working on a kit, don't know if they have it ready for production & sale yet, but here is the thread posted about a month or so ago.
I think you lose all ability of manual control with this kit, but it appears to be a very nice kit. To clarify, you lose your hand cranks, but you can still run it "manual" in jog mode. Looks very nicely made.
