I purchased my first GTP from Rocky Gravley The Arboreal Enthusiast. He has been absolutely wonderful. Very professional and prompt with replies and just all around great. And my GTP, Hunter, is perfect too. Rocky loves chatting GTPs and will happily talk to you if you have any questions about the species whether you buy from him or not.

And some GTPs do have really nice temperaments. As already stated, they are not BPs, but they can be really handlable. It helps if you purchase a juvenile or young adult and not a neonate when you can evaluate their temper ahead of time. This is Hunter with Rocky's 8 year old son.
