I recently started getting into tarantulas also and arachnoboards has been the ultimate learning tool. You can look up "bite reports" which are people actually telling the stories of the symptoms and affects of whatever species they where handling when they got bit. It gives you a good indication of what spiders to stay away from when your a newb. Because lack of knowledge and experience pertaining to an aggressive species is eventually going to end in a bite which isn't the end of the world but you might want to know what your in for since your getting some of the quicker moving arboreal species. I was reading some of the reports and was absolutely jaw dropped at the brief agony and illness that comes with some of these bites. Might be worth looking into. :)
