I would like to install a Mountain High O2 System in my sailplane. I already have a O2 bottle. Does anybody have a used system they would like to sell?
I got a deal on ebay; you have to watch for a while (I lucked in). Also, MH sells refurbished equipment on their website for good savings if you're happy to be a generation or two back. http://www.mhoxygen.com/index.php/closeout-refurbished
. Good since you probably would have to ship it back for refurb depending on age.
