Check my former posts. Long ago (in a far away galaxy)I said no large OEM/USER would buy Sigma's PR3D. Does it work .... you bet. But why would you buy the product, when the vultures can lay back, watch you go broke and "THEN" swoop in to buy up the patents. A little for this one, a little for that one. Sigma goes away and Oem's/ users cherry pick the patents for their own machines. JMHO
