Vanilla Tahitensis/Odorata/CHAMISSONIS Other Exotic Vanilla

G'Day,
Does anyone have any idea where/how I can acquire some Vanilla Tahitensis? I've been searching for it for a few years and have thus far only been able to find one source. Stock has been scarce and elusive and now the owner of the business has taken down his website and refuses to answer any of my inquiries. I did manage to get a couple of these before the owner started ignoring his customers, but they were infected by some kind of disease which was difficult to treat and now I can't find anymore. If someone could give me some kind of guidance on where/How I could obtain a replacement I would be most grateful. I would even be willing to import from oversees, if I could just find a source.
