I'm from and live in the one with the Avon, watercress and the watercress line however I work overseas and the info I gave is based on that experience.
Based in the Middle East, in the context of use in breathing gas mixes I worked with people from all over the world and travelled all over and what I've related is a global trend. Check out with your local gas plant or your local dive shop the per litre cost of He, I think it'll stop your heart. The only difference is that the industrial cylinders will come to you in higher pressures than I've mentioned
Its all a mute point, He is impractical for this application, for example running it through breathing air compressors to top off and reboost. I think N2 would work well with no special considerations other than the phaff of having to order and keep it in stock where as we're surrounded by free stuff and the equipment we routinely use is built for it.
