agreed about the henkeli, but first a question: have you ever kept a reptile/gecko before? if not, any leaftails arent really good for beginners, there is a lot of maintenance on them, they definitely cant handle neglect. im not implying that you would neglect them, i've been fascinated with them since i first got them, just wanting to help you out because without the proper knowledge on these guys, if you buy a fresh import or something from a vendor who hasnt properly acclimated them, you can end up getting a DOA or something very near to that. also, uroplatus henkeli are not being imported this year, from what everyone has said and the CITES quotas ive seen. so it might be hard to get your hands on them, although there has been a male in the classifieds if you feel like checking that out. uroplatus fimbriatus are generally a bit larger than henkeli, but otherwise very similar. uroplatus sikorae is another possibility for a beginner.
info on caresheets tends to differ depending on who made it, but try googling "uroplatus caresheet" and so on, then if theres more questions, there's plenty of knowledgeable members in this forum! welcome!
