I'm really leaning towards a new Hypertherm powermax 1000 with Earnie's comments. But, alas, ANOTHER snag in the decission making process.
I have a Coleman compressor similar to this one:

Mine is rated at 5.6 cfm @ 90psi. The air hungry powermax wants 6.7 cfm. So I'm 20% short assuming the rating from Coleman means I can run 5.6 cfm continuously. An 80% duty cycle would be fine. But Coleman's tech support couldn't say anything about the duty cycle. If they give that rating assuming the 27 gal. tank is taking up some slack and you can only run 5.6 cfm for say 1 minute then I'd have to buy a new compressor. And Coleman, for example, doesn't have a portable electric one that puts out 6.7 cfm.
Anyone tried to do something like this?
The cutmaster 75 takes 6.6 at 70 psi and the pakmaster 75 only needs 5 cfm at 60 psi!
