I'm making one at the moment. I have the use of an Excellon CNC router at work (intended for PCB drilling and routing) and I am using it to make myself a small machine for personal use. It is actually quite a simple thing to make. Do a Google search for 'diy cnc' and you will see a vast range of styles and construction techniques.
