Does anyone know a good type of tarantula?

Hi..I might be getting a tarantula soon, and i would like someone to tell me a good type. I want it to be a moderate sized one..Maybe just big enough to eat pinkies, and a not very aggressive, i was thinking of getting a Mexican Red Rump Tarantula but i found out they were aggressive. I might get a Chilean Rose Hair Tarantula, but i don't know if there aggressive/too big/too small. Or a Mexican red knee tarantula. I already have a pet spider, but its a small-ish house spider, maybe about as big as the tip of a 10 yr olds finger and leg span about 3/4 of a cm. That proves i can take care of it! =D I also have a bearded dragon, and i wouldn't want the tarantula devouring that =/ Also i have a cat, dog, hamster and fish. Also i might get a (unknown) pink toe tarantula. I dont know the satrt of the name, thats why i put (unknown) Thanks =]
