I'd point you in the direction of Nick Mutton over at Inland Reptile. He's got a few adults and has produced them in the past and may produce them this year. Not really anyone of who is active on BP.net that has these guys to my knowledge, maybe two or three guys with young'ns.
They are definitely on my want-list, and I'm hoping to pick some up from Nick when I've got the means to have 'em.
