I've got some crested, leopards, and AFT's myself (been keeping AFT's for close to 20 years now). There is another kind that's pretty cool that you don't see very often: Mourning Geckos. Ever run into them? They are all female and essentially clone themselves via parthenogenesis. Food requirements are like crested geckos, just a lot less of it (as they are very tiny animals).

The main problem I have with them is they are voracious cannibals of their own young. While the adults are happy to live in a colony together, as soon as a baby emerges they are all over it.
