Ok, looking for the wisdom of the crowd (or even just the individual) here. I want to get an oxygen setup for my glider. It's an old-school touring motor glider (SZD-45 Ogar) but I like to soar it anyway, and I live in SW Colorado so I am regularly bumping my head on the 12,500ft and 14,000ft "limits". (Why "limits"? Well my house is at 9,000' and I regularly ride my mountain bike up to 12,000 ft without getting notably out of breath, but I guess you have to take the rules seriously.) So: what is the best oxygen setup for western soaring, mostly sub-5hr flights, two seat glider, easy access to an oxygen distributor, easy retro-fit to an experimental glider, quite a lot of space in the cockpit? Oh, and budget friendly, in case the glider didn't give you a clue.

I am using a Mountain High EDS O2D2 in my two-seater and I have used it now for four summers in Moriarty. Two of us can fly several days in a row at altitudes up to 17,999ft ;-) using canuals. We never felt any signs of hypoxia. The operation of the O2D2 is straight forward - more or less idiot-proof.
Buy the biggest tank you can fit into your Ogar and still be within the CG and weight limits.

Thanks Uli! That was more or less what I had concluded but really nice to get the experienced confirmation.
