I know nothing of this product, but I see the web site talks mostly about the CAM abilities it has. Mach has no CAM, its a machine control package. You have to get that separately.
In general, I wouldn't get a "Jack of all trades, master of none" software. Get the best machine control package, Mach3, in your price range. And then get CAD/CAM software separately. I'd suggest you start with any CAD drawing package you like and use NCPlot to generate Gcode.
