+1 for the O2D2 as well.
When I first bought the plane I bought a system from Mountain High. Then I did a year of flying back and forth to Las Vegas at 8,500 and used it *once* during a trip with my brother when we flew to 16,500 to see how the plane performed (still climbing 200fpm). After a year of it sitting in the dock box next to the plane I sold it to another pilot for a few hundred less than I paid.
Then I used an oxygen generator on a trip across the country.
Blog entry I wish those had dropped in price because I would have installed a pair in the back, hooked it to the electrical system and never thought about it again. Bummer. (If not for Medicare I am convinced you'd buy one now for less than an iPad. They are sold almost exclusively to Medicare patients for $5,400 and cost (then) about $1,100 to make. It was before rampant off-shoring of manufacturing, so I bet you could get one made for $700 these days. Install it in that storage area under the luggage space, with the tow bar, get the O2D2 regulator hooked up and connected near the seats... it's a dream.
On a trip where we were going to fly north through Wyoming to cross the country
at my son's request, I ordered another system and had all four of us on it, since I knew that through the Rockies that far north I would want to be above 12,500 for extended periods of time. And I was. But I was shocked how much better I felt when we landed after the first day. So now it is along for every long trip.
