Ron,

I can't answer your question directly, I would highly reccomend you
consider the MH system. The great thing about the MH systems do is
turn on and off automatically at the altitude you select. I set mine
to 12,000 feet and forget it. It comes on when needed and turns off
when not. The price is slightly more than the aerox but I think you
will love it in the long run. Uses a simple canula and can mount out
of the way.


Steve has a used DD1 unit on eBay that is overpriced by about $250.
You could likely get it for the price of the Aerox system if you
contact him directly.
