We had a boa in the household when I was a kid. I do not know what kind it was but I seem to remember it was colored more along the lines of a normal BP - nothing fancy like a red tail. But, I used to play with it when I was but a wee little tike. It only lost its temper twice: Once I tried to "introduce" it to the dog. It promptly struck the dogs nose. The second was a time that I tried to forcibly unwrap it from the leg of a peice of furniture. It only hissed at me then and it didn't hold a grudge either.

There are a number of size-limited pythons to choose from too. I was at the store I got Snakey from the other day and they had a carpet python out. It was definately a cool snake.

They have some boas in there that I would bet ended up there because the owners didn't want them any more. They are just massive - 5 inches thick with a head that would fill your palm nicely. They just don't appeal to me at that size for some reason.
