Difficulty of Rainbow Boa?

[Loppy]

I currently have a 11 year old Ball Python that I raised from a baby and a Gopher Snake that I have had for 4 years(don't know how old she is, as I adopted her after someone abandoned her at my apartment complex).

I love my two snakes currently, but my absolute favorite type of snake is the rainbow boa. However, I was told that they were not beginner snakes which is why I have waited so long to get one. I am currently considering finally getting one, so I was hoping to ask some of the snake experts here if they have any advice on this type of snake or know of any good breeders.
