If your talking about a blu ray like a dvd recorder I don’t think they are available here yet. Japan has them, maybe other places willing to spend the sort of money they want for them right now.
Other problem is expensive blanks, but hopefully that’ll change soon. I think the external version for PC’s are still going for 350 or more right now as well.
I think for now there just aren’t enough of them in the wild yet but we’ll see what those in charge say.
