I've kept a. avicularia and avicularia versicolor, both are gorgeous but tend to be jumpers when handled and need high humidity, I've also kept grammastola rosea and grammastola pulchra, both of which I love and recommend as beginner spiders. The only brachypelma smithis I've dealt with have been at the shop I work at and were hair flickers when we got them but calmed down pretty quick.
