I bought mine from HF several years ago and it is a true RF (at least it says so on the name plate). I have converted it to cnc and have been very happy doing so.
Realize No. 1 that it is a round column machine so that means you need to spend more time in doing your setup to get around the problems of moving the head for tool changes, but with a little foresight, it is not really (to me) a problem. It was a natural for conversion as the lead screw/nuts are junk. I had a problem with backlash (up to 1/4") prior to the ball screw conversion as the combination just got sloppy and no amount of tightening could reduce it. Along with this, the X nut would actualy slide in its mounting contributing to additional backlash movement. This was solved by "pinning" the nut to the table after alignment.
Depending on what you are going to cut, check out the actual required table movement. I have in a few cases been shy of what I really needed particularly in the Y axis. (after cnc, I get 7"). Rigidity of the machine is at best fair, but then again this is relative. What are you going to cut. If plastics or maybe aluminum, ok. I find it a little weak when trying to hog steel and ALWAYS be sure the column clamp bolts are tight. You will chase your tail if the darn column rotates at all with cutting action (again especially in steel with agressive cuts).
Bottom line, for typical work that I do it has been a good machine and for the price, if I was starting over again and know now what I didn't then I probably would do it over again IF I decided on a bench type mill.
Hope this helps.
