Information on Xenopeltis/Sunbeam?

They're beautiful and I'm considering getting one next time I have the money to buy a new snake. I've been surfing the net and so far I've found these care sheets:

http://www.kingsnake.com/rockymounta...RMHsunbeam.htm

Those have given me some idea of what to expect, but I was wondering if anybody here has any more information? Does anybody here keep them? If you do, do you ever see them? I'll admit the main appeal is the lovely rainbow effect. If they never come out of hiding at all, I'd be disappointed.

Also, so far I haven't yet found a single breeder or source for captive bred individuals. (Heck, I haven't even found anybody who imports.) I suspect I may have my work cut out for me finding one. Anybody have any suggestions where to look? Nobody here or on kingsnake seems to be selling any. I really would prefer captive bred or at least captive born, I don't want to deal with an import that's going to arrive stressed half to death and parasite ridden if I can help it, not to mention that I'm hesitant to support an importer who may or may not be harvesting these animals in a responsible and sustainable way.

I'm not buying one any time real soon, but I wanted to be prepared, so I figured I might as well ask.

We had a couple of these a few years ago. They are beautiful, but the only time we ever saw them was when we took them out to clean their cage. That's why we decided to sell them. I haven't seen them around in awhile, but hopefully somebody else can help you with that info.
