Power Survivor 80E alternate membrane options?

[LadyStardust]

Has anyone found a source of membranes for the 80E other than the official Katadyn ones. I'm assured they will exist, but until I remove my existing ones, I won't know if they have markings that help identify them, and I'm not able to do that right now.
