I have also been putting together an O2 system as well and in doing
considerable research found that I could easily put a system together
a brand new system for under $250 equivalent to the ones that the
"Soaring" sites typically charge $350+ for.
I get the mask, canula and flowmeter kit ($95) from Cumulus soaring
and the Cylinder, Valve and Regulator from the cheapest "Medial
supply" place ($60+$40).

The price seems to be getting inflated on the O2 cylinder and
Regulator but if you compare specs you will realize that the typical
13 cu.ft "D" size cylinder only costs ~$60 from medical supply places
instead of $215+ from an Aero supplier and a functionally equivalent
regular can be had for $40 instead of $170.

The cylinders are identical in size, shape & specs and come from the
same factory (Luxfer).

Also, the oxygen for ABO(Aviator), Medical and Welding all come from
the same source and be had in the same composition, but if your bottle
has an ABO or Medical sticker they are only allowed to be filled from
a single specific source type, narrowing your filling opportunities
considerably.

You are best off getting an unmarked bottle and filling it anywhere,
Scuba shop, airport, medical supply(with prescription as they
typically dont know they can supply pilots without one) or welding
supply.

There are also "Electronic O2 conservers"($300 Devillbliss) at half
the price of the "Aviation"($600) one I have seen, but I did not
research it enough to know for certain if it is equivalent.
