Don't know if you're still in the market as you posted over a year ago, but there is one for sale
in Nanaimo right now. They had it listed at 11995 and now reduced to 9995. There's a link in these forums somewhere...but if you just google Bonair Oxygen
...it'll be on the first page. There is one here in Ontario as well...but it's 13995 They don't come up very often.
I'm located on Vancouver Island in Canada. I saw an Oxygen for sale in Vancouver a couple of years ago but didn't connect with the seller. Please let me know if you see one for sale.
