The way I see it is there are two facts:
Deserts make awesome combos &
Females have reproduction issues
My thought is this should keep the desert gene going, as it is much harder to produce combos. Therefore, prices should not drop as drastically. While on the other side of this, if you want an awesome looking snake, with no interest in the breeding, you can also pick up the same combo at about 1/3 of the price.
To me, sounds like a win win for both breeders and those looking for an awesome pet.
That is what made me to decide to buy my breeder male this weekend. I will also be on the side of the fence where until there is conrete proof that they at no point will ever produce viable clutches, I'll be holding a few of my females back. I will definately not give anyone looking to buy one the impression that they will breed, however. Full disclosure here.
Just my opinion of many. Feel free to agree or disagree.
