Hi, mine is not a morph. The Barranquilla is a locality in Colombia. Believe it or not he is I guess, a "common" boa, but not really.
You can look at Hog Island boas too, and if you have a slightly daring side, you could look at a male BCC. They are just beautiful, but tend to get a little larger, that said, the colors and contrast are amazing.
I personally would not spend huge money on any morph. Kali seems to have a good connection and gets her stuff at reasonable prices.
If you are just starting your search, really, really prepare yourself with caging, heating and all the stuff. The cage stuff is a lot of fun!! I think you'd be surprised how unthreatened you'll feel by a larger snake. An 8 foot female Colombian boa is considered large. But in reality it's not that big. A 6-7 foot male is normally less massive and much lighter.
I suggest you pick your snake well if it will be your only snake. Really get what you want and love it. $100-$300 is plenty of money to get a quality boa IMO.
Here is the difference between a Royal and a BCI. The python is a female (2yrs) and is a year older than the boa (1yr). The BP is my son's, and the male boa is mine. Look at the colors in the sun on the boa. Not a morph, just that pretty!
Having a nice display cage that is also tailored to your boa's needs is not only healthy for the snake, but really pleasing for you and others to look at.
If you do everything right from preparation to animal purchase, I think you'll be rewarded with the perfect pet.
And BTW Kali,, another set of beauties there!!
