live out west and have been debating for a while.

Anyone know of a good place that fills tanks in the Phoenix area?

I have a normally aspirated aircraft and I live down here at sea
level. I regularly get up to 10,000 or so and sometimes higher.
I like having the portable system. Tank filling is hardly anything
and it doesn't need to be done that often. All of the oxygen
system vendors will top your tank off at Oshkosh (and probably
other shows) as well..

My tank usually only lasts one trip but I have 4 people breathing it
(I have an 'E' container which is a bit larger). I'm in California and
my normal Eastbound altitude is 13,500 in my non-turbo Mooney.
Anything lower than that is a bit scarry between down drafts and
dodging rocks. A normal trip is about 6 hours each way so about 12
hours on a tank with 4 breathing it.

However, it depends on where you fill it. If I fill in California I
get a good fill. If I fill in New Mexico I get much less because of
the altitude.
