Who was the Plasma cutter guru here?

My adapted S45 torch head worked, it just wore out the electrode pretty fast. maybe thats just by design. Just wondered if there was a P30 repalcement. Its a wonder how many torch heads are out there for basically 3 types. HF, contact and pilot arc. The complete replacement 30 amp P30 torch I found is $10 less than a brand new Chinese CUT50 rig shipped, and those work pretty good for the hobbyist.
