The M-30 is coming out and it's a concentrator. It will put out 20 LPM at 30 PSI, which is a LOT of Oomph, for much less $$$. The M-20 is what JC is running her Cuda on and she's loving how it melts boro. I haven't tried that set up myself, but the expensive generators are a thing of the past in my opinion.
