We use Sky-ox and have been happy with it. We've noticed there are enhanced features but haven't bought them. Don't know if capacity will be a problem for you.
I would also recommend getting an oximeter to make sure the pilot's O2 level is good. It was not the plan but once flew at 15,000 for about 10 hours and my decision-making and mental acuity were not good. Thankfully, I was co-pilot and recovered immediately once we descended.
