SO many pangeas so little time...lol
Like Donna said, as far as easy of care and breeding, cresteds are the way to go. And also raising them, it will cost you more in food costs to raise leopard geckos than crested geckos as they are not required insects. Also the link she posted....seriously read it, read all of it, if youre interested in crested geckos, there is so much info in there, anyone considering breeding should take the time to read it.
The downfall of leos and cresteds, everyone and their grandma breeds them now, even if youre not in it for the money, everyone wants to at least break even, and with crested geckos if you dont have project goal in mind and breed for some sort of quality animal, your average gecko produced from average or less than average parents, you may not even break even when you figure in the cost of the adults, their enclosures, the decor, baby enclosures and baby decor. It can cost alot to get started with crested geckos over a leopard gecko simply because of different setup required. So unless you spend the money on nicer animals, you wont break even for a few years, and then you just added to the supply of less than great animals to the market, and the cycle can start again with those people who realize just how easy they are.
But the same with leopard geckos, they are so easy to breed and raise, and although there are not key traits for buying a leopard gecko like a crested gecko, crested geckos you have a number of key factors besides color, you have crest structure, head structure, lineage. For leopard geckos lineage knowledge does help, but there are just such deciding factors in what is a good quality animal, and what is a bad quality animal, it is more about what morph you want to produce. With a crested gecko, people want several key things, color, contrast and structure, all very important things.
I think before deciding to jump into a species to breed them, try buying a few babies and raise them up to see if that species is really what you want to work with, buy a baby leo, baby crested, and a baby fatty, see which you like the best, then go from there. For one baby cresteds are harder to raise, so it will give you a firm grip on how to take care of babies, and possibly be ready for 8-12 babies from a single female to know if that is an under taking you want to do, or if you find fatties are the sweetest little things ever and you feel the need to be surrounded by them
