I got this thing back in 2012, and I finally will have the time and money to do it. Unless otherwise advised, I'm probably just going with the "kits" from Automation Technologies/Keling...
I do need four axis, so my main concerns at this point are an operational fourth axis that will be capable of use with free machining steel and 416, and I'm considering either one of the ebay harmonic drive setups with a chuck and tailstock for about $500ish, or a rotary (and I'll likely need help with that...).
Any thoughts?
