¡Dave, the best thing to remember is just about all spiders are venomous and can bite if you let them, so don't let them. There are some dangerous spiders in Brazil but there are also some fantastic ones that are pretty harmless. There are quite a few tarantulas and they have never been known to kill a human. The ones in Brazil are new world and so have a milder venom and are less likely to bite. They have urticating hairs which feel a bit like fiber glass when they get on your skin, and can irritate quite badly. New world T's will rathther flick hairs than bite.
Shakey, my B.smithi is typically docile and gentle. She is a great show spider but has issues with her water bowl, but very nice.
magowen100 I have two juvenile Avicularia purpurea which are dark purple pink toes. I've had them since slings and just starting to get adult colourations.
Hadge, nice N.Crhomatus!! Looks lovely and healthy. I mainly collect African and Asian Tarantulas with a few funnels webs and true spiders. Though a friend is sending me some young centipedes from Singapore and they look fascinating.
I also have a commune of 6 P.regalis which are just about ready to be re-homed as they are getting too big for their enclosure. Herding six should be interesting.
