It looks a nicely built unit, but at that price, it should be!
I fitted a DC motor to my Dore Westbury mill/drill, and got a KB Electronics Board to run it - about £73 from STM in Winsford. I had to box it up, and concoct a no-volt safety switch for it, but that's only a 10A mains relay with a mains coil and red and green pushbutton switches.
