Not sure if you found one yet but I got one from my local nursery in December. Clown Alley Orchids, Pasadena, TX. You will have to call to see if they have it in stock but they will ship worldwide.
I ordered one from Fantasy Orchids some weeks ago, but the poor thing is unfortunately not in very good shape. It's tiny and some large sections of it look like they're threatening to die, so there's no telling how long it will take it to actually get around to blooming even if it lives.
So I may very well look into ordering another one somewhere else. Thanks for the tip, Mollie!
