@Vixorthegreat In the US, it seems to be about impossible sadly. The most recent person I found received their Hyllus from a zoo keeper friend, and that source is looking for them too.
The last I seen them for sale, was when they were sold out of course, over at CCR here. Otherwise I have contacted people in Youtube video's that had them, arachnid sellers, and lots more people. I never have found one for sale, and only have accumulated a list from those I talked to wanting me to let them know if I find any extra ones for sale.
