Who was the Plasma cutter guru here?

Once again, Im on the hunt for the original torch head for my Marquette 12150 (System 3015) 35amp plasma cutter. I think I have narrowed it down to the Cebora/Snap-On P-30 torch but seems no one makes them anymore, Is the P-70 the same or close enough? When I got it, it was headless. I just need a compatible replacement. I dont know if its a HF or pilot arc. The Trafimet S45 torch head electrode gave up on me. As I understand it, I was forcing a pilot arc on the wrong torch head and it was sacrificing the electrode. Weldmart sold an "Alpha 3a" replacement torch (it added pilot start?) for it but its no longer available and it listed the M12150 as a candidate. One of you helped me out a few years ago and I forgot who it was.
