My available is empty, because most of my animals are selling as soon as I post pictures of them, and I have a few more that I want to have feeding before I post them. That may be why others also don't have links up. Like someone else said, e-mail the folks you are interested in, and see if they might have something they haven't posted yet that you're looking for.
Speaking of which, many of the animals I've acquired in recent years have also been from immediately contacting someone when they post pictures of babies they've just hatched out if I see something I may be interested in and inquire if they plan to hold the animal back, or will be selling it, ask the sex and the price.
