I have seen them offered in my LFS
a couple of times so I know they're available. Just be sure to do as much research as possible. And when they mention escape attempts, they mean, they will climb right up and out of yoru tank and the only hard part of their body is their beak, which mean they can, and do, squeeze themselves through just about any opening they can find.
Keep us up to date, I'd love to see how your research progresses.
