Plasmacam is a good choice, I have had their machines for over 15 years, easy to learn, easy to use. I suggest getting the advanced Design Edge software and advanced height control options, will be worth every penny over time. You may want to post this on the PlasmaSpider.com ? Index page as I think there may be many more Plasmacam users on that forum. You are welcome to come to NH and take a look at mine.
