Like everything it is all preference really. I use CandCNC electronics on my 5x10 table with Sheetcam as my CAM and Mach as the controller for the table itself. Mach can be intimidating until you get all the bells and whistles set but is a piece of cake then. Mach is the generally preferred controller for smaller outfits and self built machines like mine and is one of the reasons I built my own. Just did not want to be tied to a closed architecture control system that tied me to one company's apron strings. JMHO
I've never found a bitmap to vector conversion program that lived up to the hype they tell you.
