I live in the UK and I would be very surprised if these are available, I have never seen one in a rep shop and probably never will.Maybe the odd one gets imported from time to time but they certainly aren't a craze. Nice lizard though.
I live in the Uk, and I can assure you that this is an example of media bias against reptile keepers. There really isn't a craze surrounding these lizards. I'm sure some get imported, like many other species of Agamids, but to call it a craze is very overblown.
