I agree with RG. Avicularia sp. is NOT the best species to start with. Arboreal tarantulas in general are not the best. Many first time keepers have Avicularia avicularia (common pink toe) as a first tarantula but that is about the *only* Avic. species that is hardy enough and docile enough for a novice to feel comfortable with.
I would steer clear from *any* Old World tarantula. Old World being any tarantula from Africa and Asia respectively. Central and South American and island tarantulas such as Nhandu, Lasidora and Theraphosa tend to be more skittish and more prone to aggression than those from the United States and Mexico.

To give you a place to start, look at Aphonapelma sp. Brachypelma sp. and Acanasccuria sp.
