There seems to be only a few out there in collections. They're not easy to get on a list for and are rightfully a little pricy (not over priced, I'm just comparing other Asian specie prices) right now. Some only have lone males or females right now, but should be getting mates for them this year. I think you mentioned and thanked Sacha Korell on these. Good luck; they are looking real nice.
:I just got this photo back with some others and thought I'd throw it up. Not too many of this species. The pair I have is going on two yrs. old and are holding their color pretty well. They brumated three months and came out real hungry, so I'm pretty happy with that :) :
