Im not at all interested in breeding any hybrids. But you're right, alot of people breed Cranwell's and they are very well established in the pet trade. It would be like breeding regular colored Leopard Geckos at this point.
Ornates would be interesting, I've never kept one. I've read they have multi generational breeding problems. I'd be interested in Cornuta, but there has been no F2 success with that species. I have been seriously considering breeding breed Stolzmann's Horned Frogs, and purchasing a group of 4 to 6 from Understory Enterprises.

I've also been considering breeding Budgetts Frogs.
