The GCC Puma is by far the superior cutter.
What software is bundled with it?
SignMaster is Vevor's version of VinylMaster. Same thing.
If you are designing using Illustrator, then, yes, just Import the resulting .eps into SM and cut.
Just a suggestion, but since you're already doing paintwork on wood, maybe try decorating a few Cornhole boards, and sell those!
