If you wait for one of Little Leaf's babies, you'll get the happiest, healthiest, most loved baby ever. They would certainly be worth the wait
There are CB Jax out there, but yes, they can be difficult to find. It seems like the supply isn't quite as regular as for some other types of chams. I believe FL Chams are CB, but you'll want to check with them directly. There are probably some other forum members who have Jax available.
You'll also probably want to wait until after Xmas anyway - I would worry too much to try to ship a live animal during the holiday package overload. To much opportunity for delay.
