Move at will...

I've been thinking about getting a BCI for a few years now, partially because I want one and partially to get rid of my excess rat population when they grow too big for my ball pythons and then I'm stuck because my ball pythons are on hunger strike. (Rats cost more than upkeeping snakes on food bills...)

I'm looking for a female with sable coloring and if it's possible, some blushing, but I'm not sure what regionality would be best for the kind of thing I'm looking for or boa breeders. I'd prefer to have a boa that doesn't get too big, which is why I'm looking at BCIs, but still can take a full grown rat when fully grown. (So doesn't demand rabbits eventually or whatever).

Are there reputable BCI breeders who offer pictures of their animals? I don't need anything beyond a normal... I think.

Ideas on breeders and regionalities for these needs?
