Vin Russo is a good one that I've purchased from. I've also heard great things about Gus @ Rio Bravo Reptiles and Paul Mitchell @ PM Herps. As usual do your research and check various BOIs before making a decision. Getting from a specific breeder doesn't matter unless you like the animal you would be purchasing. Happy hunting!

And I have gotten 3 boas from Tim at Special K Reptiles. He has been a pleasure to work with and will take plenty of time with you. Will answer any and all questions before and after purchase even years later. And all 3 of my boas are super healthy and very aggressive eaters.
