I have had a 480APC model (a 480 with a front mounted pallet changer). The machine has made a lot of money over the years but the 20 tool side mount changer barfs every year or two by getting full of aluminum chips. The machine seems to be more rigid as a Haas, it is fairly quick, and overall a pretty good machine. Support from Hardinge is ok but not great on the Taiwan machines. Is the one you are getting new or used?
