I've been saying this for some time now, the advancement in Rotary machines would sound the death knell for air powered rotaries,which to me is what they are. Nobody wants an air compressor in their shop that makes machines sound like dentist's drills. The first time I heard a Neuma in action I thaught no way for me.
Pert, I would accept whatever you can get at this time,as I honestly believe a year or so from now,you won't be able to give them away.
