On safari we carry a trans-fill hose and rent a bottle at the local gas
supplier. For less than $50 many gliders can fill up for a week. The
hose was the expensive part but I found a hose with pressure gauge at a
veterinary supply house at an extremely good price.

It has been my experience that Medical Oxygen requires a prescription.

Most Welding Gas supply businesses have ABO Aviators breathing Oxygen no prescription required and can fill a bottle.
