Hypertherm 30 is the only choice as far as I am concerned. They are the best. BUT... I have been doing all this fabrication stuff for years and have decided against Plasma. Its not accurate enough when it comes to thicker materials, and not necessary with thinner materials since a body saw or thin disc works without completely messing up your shops concrete, dust and soot everywhere, just not for a clean freak like me. I have given this LOTS of thought. A nice band saw would be better. just my opinion.
