If you (Yellow butty box) had read another of my posts with regard to how much I have been paying for helium and how much I could soon be paying you would see why cost is my main reason. 3p now and soon to be 5p a litre.
Who would pay £150 for gas to do one 70m dive when you could pay 10% of that? When I get my YBOD it will have paid for itself in less than 2 years.
