Honestly, I would recommend brevs to start out with. The leafs are just as addictive as the rest of them, and you can always move on to other species later on. Brevs are a worthy project, and inexpensive to get in to. They are more active and colorful than.. well.. just about any other leaf chameleon. I really like my superciliaris, but if I could only keep one of the species, I would choose the brevs. They are just so.. cool. Plus, there is more data on them than the other leafs, and a few of us are having some good success with them. They are still challenging, especially if you plan to breed several generations. This is one of those species that everyone will regret not having worked with more when importation of them ends.
