One thing I can add with regards to Brachypelma species. They are classified as "beginners", but if you read up on B vagans, they are mean, my B boehmei is quite active and will readily attack anything in her enclosure, is quite fast as well, so could potentially escape.
Even my Brachypelma albopilosum (curly hair) will bite the paint brush when it is hungry, so handling it when it hasn't eaten recently is quite difficult and risky.
The reason I am mentioning this is because many beginners get a tarantula with the idea of handling them, I know I did, but later realize that they can be appreciated just as much without removing it from it's enclosure.
In the beginning I have coaxed my Ts with my bare finger on many occasions, but again, last night, my B albopilosum attacked and actually bit my paintbrush, had I use my finger, it would have surely bitten me.
the reason I was poking at it was to get a nice pose for a photo, but I have done this when rehousing or when trying to show it off to friends and family and it attacked the brush. Then no one will believe they are a pet rock.
So, the bottom line, not all bBachypelmas are "Friendly" and good for beginners, especially the B vagans. (My mature male is very nice though)
