You will have to literally stumble on one to get it for $75, I stumbled on one but I paid considerably more for it. From some other sales I have seen some of the machinists will pay over a $175. I have already turned down one offer of a $125 from a local a machinist. I don't need mine, I just wanted to see if I could make it do what I wanted to do. After I set it up and got it working, I was happy, I proved to myself it would work. Now I am back to using my own mini mill set up using my wood lathe as a horizontal mill.
