What is the cost of having a steady rest commercially printed for either an original Unimat or a Unimat 3, or who is selling printed ones and for what price?? I want to compare printed ones to buying original on?Ebay.? ?I am also thinking that I can sell an original one on Ebay if I no?longer need it, but maybe a printed one has little resale value? There is no need to tell us that you have this great printer and CAD system, you can design and print your own, for almost no money.??
