I'm still partial to Vectric. Most of the people here use it, so there's a bonus.
With Vectric, I believe you can save your toolpaths and then use them if you buy one of the products. MEBCWD can tell us exactly how that works.For the other person, I have not used vectric yet because last time I looked (was when I first started with CNC stuff) the limitation of not being able to save the toolpaths bothered me.. although I suspect you can just regenerate them, I'd have to look into it more..
