I'm looking into getting a mini mill to convert to CNC. I need to know people's opinions on what is a good mini mill to convert that preferably costs under $700. After I get the mill it won't be a problem doing much of the converting because I have a knee mill and if I'm lucky a HAAS VF3 to use at work for now. I've got drivers for a machine I just need to get the components and solder them together.
