Thanks guys alot of info in here, I don't really do sculptures but if I do it's through a 3d modeling program which I use autodesk 3ds max and then into Zbrush for finer details. Most of my work is through 3ds max just because I've used it almost on a daily basis since 2002. So the majority of my work would have to be converted to stl and then through a cam software. I'll have to start doing some trials on some. And BTW you think aspire is expensive I remember paying 3.5k for 3ds max when I did my freelance work.
