Welcome to the forum.
I have not heard of that seller either, and I have been looking a lot of them lately looknig for my #2 ball python. Are you near any areas that have reptile expos? If so, I would recommond going that direction. The prices are generally a little lower, and it gives you the chance to meet your snake in person and talk to the person who's been caring for it. I found that helpful. BEL's are very pretty, and I can say after just having my first bp for about two months now, You're going to love it. They're just so darn neat!
Have you decided on what kind of enclosure you're going to use? I learned that is just as important (if not more so) than they snake you want to get.
