Their prices are hidden unless you're logged in.

Another site charges $18 for the CGA540 option. But the spec'd volume on their D cylinder is odd.

I recently bought 2 D size alum cylinders from Mountain High for $205 each. The fit perfectly into my new ASH31Mi with the factory supplied cylinder fittings. I also bought a M122 alum cylinder (3455 liters) from wtfarley.com for $299 and a CGA540 trans-fill adapter from ebay for $70:

Everything has DOT stamps - no Euro crap. I got the M122 filled with aviator's O2 at the local Oxarc for $40 (aviator's O2 is regular O2 that has been tested for moisture). By way of comparison, filling a single D2 cylinder at the airport typically costs $40. This should cover me for an entire season of soaring and pay for the cost of the equipment. And I can fly from ANY airport, including those that don't have O2 service. Note: you can fill ANY cylinder you want from your own supply cylinder - no DOT stamp required!

A very good PDF about oxygen and transfilling.

Just spoke with Bound Tree. They have sold all of those steel D cylinders. Tried EMT, but got voicemail.

Where does the O2 cylinder fit in the ASH31? Same as ASH26, behind your left shoulder?
Al cylinders don't fit ASW27, 28, ASG29 which have a tight tube behind the seat back on the right side.
Anyone having a problem finding the steel D required for 27/28/29 could modify the baggage compartment like 27058, allowing the use of an "E" sized Al cylinder.
This does not work if you have a sustainer.
There's a photo of the baggage compartment of 27058 after the O2 mount and extractor mods in the ASW27 newsgroup. Or:
