Speaking of oxygen, is there a good place to buy it when your traveling other than airports to save a buck or two or is in not worth it.

I get my O2 filled locally at a surgical supply store.  Saves me about $20 on each fill.  If I was on the road and had a car and access to Yahoo yellow pages, I might try searching for "medical oxygen" or "surgical supply".

I have a skyox system.  Will I need any special fittings to fill it at a surgical supply store?  I dont have my manual with me.

By specs, aviation has less moisture perhaps. In practice, I've
actually been in the facility where our hospital, airport,
and welders fill their O2 locally at a gas supplier....and they
all come off the same tap.

Done numerous hundreds of deep dives using commercial helium,
and done hundreds of hours of decompression using welding O2.
For welding, they require purity. Argon may have some
differences, but since I just used that to fill my suit
I didn't care.

Concidently, I'm taking my O2 bottle in this afternoon to our local
welding/medical/aviation gas supplier to have it filled.

Reportedly NONE.  I called a medical supply place and they wanted $18 for a refill
plus I needed a prescription since O2 is a "drug."

I'd be surprised if you need anything special.  I don't know the hardware or terminology very well, but if you can remove the regulator from the tank and the tank has a male threaded valve about 1" in diameter, it's probably "standard."  I'm pullin this out of my butt so forgive me if I'm wrong.  Worth trying if you find a cheap source.  For example, the local surgical supply place charges me $10 for a 13 cu ft fill.  Hard to beat that with a stick (I looked into self-fill options with tanks and this was cheaper all said and done).

That's a very good article and pretty accurate. Last time I swapped
my 250cf O2 cylinders it was $20 or maybe $22. Having owned about
26 of these various large cylinders in extremely large high-volume
cascade systems, I can say that after the investment, you would
definitely be flying on O2 for cheap. It's not for everyone, but
for the D.I.Y. person it's perfect. Get a good fill whip.

At one time there was a difference in purity and moisture content but
these days it is all 99.99% pure and comes out of the same tank. The FDA
views oxygen as a drug so you cannot take your medical O2 bottle and
have it filled without a prescription. That's about it.

But I can get O2 without prescription to do some welding with it.
Funny logic, isn't it?

Went to a local surgical supply store to inquire about filling my ox tank. Got a "can do" BUT, will need a perscription as despensing "medial" oxygen without a perscription is a felony - or something like that.  I would guess that any local AME or doc you have a friendly relationship with would write you one.

I suspect this may be in error...I just picked up my oxygen bottle from a
medical supply store in town today for $12 and no prescription.

It was based on this article that I went welding Ox about 4 years ago.
It was not as cheap a solution as I had hoped.
Got to buy an ox welding tank in order to be able to exchange for refill.
Had to buy the adapter filler cable to go from Welding Tank to Medical portable tank.
Had to buy that darn fingertip Pulse ox sensor to monitor like this one http://www.scantechmedical.com/onyx_ii.htm
Had to get the little Nelson A4 in-line flow meters like this one. http://www.airportshoppe.com/aviation_oxygen/compared.html
Had to get the oxygen saving cannula with the little flapper valve built in to conserve ox.
Blah Blah Blah.
 
My welding tank swap costs me $21, and it will refill my D size port tank about 6 times before pressure drop under 2800psi.
 
In the end I like the flexibility of filling when I need it. But this is not a cheap endeavour and Ill be years recouping my cost.
I use this much more with my Super 8 than I did in the 6 since the S8 gets to altitude faster and cruises better there.
 
Best,
Mike

I'll take a shot at this.

YESTERDAY:
Oxygen was compressed by compressors. If they did
not use things, such as charcoal filters, it turned out to be
welders oxygen. If they took out the water it was aviation oxygen.
If they put "so much" water back into it it was medical oxygen.
TODAY: They compress it into a liquid. Of course that is very
cold stuff and in the process the water freezes so there won't
be any water in the LOX. And since it was processed without the
use of standard compressors there won't be any oil in the LOX.
SO NOW: where ever you fill up you will have clean oilless,
waterless, oxygen that will never ever fail you at FL180, unless
you happen to be bying from a place in Egypt, Rumania, west
podunk or someplace like that. I have to believe that worldwide
non-standard processes are the reason the FAA still clings to
thier FAR's regarding the source of oxygen.
That's my story and I'm stuck with it.

Is there any reason that a small medical oxygen cylinder and canulas not be used in an aircraft.
My father, who passed away, had medical oxygen equipment that I now have. I can not see any reason I couldn’t use this in my plane.
Am I wrong?

Will work great in your plane!
But he probably has regular cannulas.
Practically speaking, you would want the ones with the little flapper in them like the one on this page.
http://www.airportshoppe.com/aviation_oxygen/compared.html
or this one
http://aerox.com/Pages/masks.html
 
Really saves the oxygen. I could pull a tank dry in 3 hours on a std cannula at 18k’. I can go twice that with the flapper valve one.
