Cheap OX recomendations

Any thoughts on a simple, small, portable medical grade system. Cheesy vinyl
mask and small bottle? Where can you fill them?

Actually, it's easier to get ABO than medical oxygen. Federal law prohibits dispensing
medical oxygen without a prescription. Go figure. Any gas shop will fill it either way
(all the same gas). Look under oxygen in the Yellow pages. Oddly enough, since most
of the airports here are ringed with industrial park, you usually don't have to go too far
from to find someone to fill it.

I know that the FAA/reg guys would have a field day on this, but I'm also thinking along
the lines of a SCUBA "spare-air" cylinder. Smaller than a normal thermos bottle with
built-in regulator. You wouldn't use it continuously (so no good over 12.5k), but just
to take a few hits every once in awhile and before landing to "freshen up."

Precise Flight/Nelson makes these. I posted a link earlier.
