They are not a very common lizard.
It's odd considering they go for about the same price as chinese water dragons (love those guys too!) imported anyhow (the pet store I first discovered mine at jacked up the price to $69!).
They are super lizards, beautiful, gentle but shy. I NEVER saw mine eat a cricket yet every time I went to refill his food, he had no cricket parts anywhere. haha! 
Anyhoo, I'll email Mark and see if he knows when he's getting more. He's cool, and carries some spectacular animals. 
Thank you again and I'll post here again with any news of these guys coming in.
Hugs!
