My deepgroove mill is running great so far. Legit and timely for sure, but I have read that his support is not that great. I haven't needed any support, but he is quick to answer e-mails. His controller is the gecko 540 in a nicely done box with a good power supply, and the steppers are dual shaft, 4-wire, bipolar motors.
It took a while for me to find out what cad/cam software to use, but Mach3 took less than a day with no experience to get the machine running 2d engraving.
