Just keep in mind they may not be as rare as you were led to believe is all. They do look nice but if he is selling them in actual numbers its because they've already been bred for this trait therefor there could be hundreds or more.
If you want next time Im at the importers down in FL i will dig through what they have and see if I cant find you a few more. They go for about $2-$3 each down there.
