Suggest you try Henry Batten, Batten Reptiles, just had 3 07's, 2 norms and 1 het pied from him, all healthy and feeding well, all have great temperments, they are all Bob Clarke line, sure he would be able to help.
If only i had known you were after one, i want a female crestie but i see they are all gone now would done some kind of swap with you for one of our royals.
