my total conversion of a round column cost about $2200 to put together. it was a pretty steep learning curve. i would do it again, but this time i bought the IH mill and kit. unfortunately i still have to do all the wiring and that was what gave me fits on the first one. i really built the first one as a template before i build the IH. the tormach cnc is an option but then i don't want to worry about lost steps with steppers.
