Greg,
I have been looking at the Thermal Dynamics and Hypertherm units but they are a little higher priced than that. I am going to an auction tomorrow where they are selling a Hobart AF 400 Plasma cutter so I may buy it if the price is right.
You might look into this company. I think they are built overseas but they are supposed to be a cut above the rest.
