I don't think a plasma cutter is as easy to master as it seems. I had a neighbor that's a custom knife maker. He cut his knife profiles with a band saw for decades. He finally bought a plasma cutter but after spending about a year, off and on, trying to get use to it he gave up and went back to the band saw.
I have a moratorium on buying new tools. Maybe next year I will give a plasma cutter another look.
