leaf tail geckos

[chamitch1]

there not to common and i wanted to order one through my local pet store. and i am thinking of the mossy leaf tail or satanic leaf tail. crestie would be neat but these are a bit less common and i think look cooler. is there any husbandary difficultys taht i shoudl know of that are keepign them from being as common as other geckos? any other types of nocturnal semi aboreal geckos that are neat?

thanks
