Good beginner tortoises are A. horsefieldi "Russians" and T.g.ibera "Greeks", both captive hatched and raised. Also T. marginata, Marginated tortoise. I like them because they are hardy, coming from climates roughly similar to what I can offer here in Northern California. I would expect to pay about $100 each, perhaps a bit more for marginata. Perhaps a bit more on the East coast. With a little looking, you can find captive bred specimens of the above, which are typically less problems and usually cheaper in the long run than imports... I evolved into tortoises only about 6 years ago after some 35 years with snakes and lizards. They are fun, lot's of personality in the above species, and house guests aren't afraid of them! Good luck, Vic
