Thanks for the name calling. I appreciate it.
BUT if reading comprehension is an issue here, perhaps I should move on and let you real sign pros debate the OP's original question by veering into your narrow world view territory. There is more out there than just Corel and Illustrator. In fact, there are super cheap apps on the iPad that are vector based, and if you email them to yourself you can cut them on a real plotter. I was a beta tester.
He did specifically ask for something free or cheap, and was only wanting to concern himself with simple vector work. Bells and whistles are beyond his need and by the sounds of it, beyond his budget.
I happen to know of a vector program that IS FREE (InkScape), and I do use SignCutPro, which is a step above free, like SignBlazer.
