LAC Herps is a reputable breeder with some stunning animals.
Chahouas make great pets. Hand raise them from babies and they will be awesome as adults. I used to have an adult male that I got as a sub-adult that became cage aggressive (I didn't handle him as much as some of the others), but once out of his enclosure he was fine. They are fairly similar to cresteds but they get bigger so they need more space as adults. They also need more quality insects in their diets in addition to the gecko diets that are generally fed. They do best when housed alone (unless paired for breeding). Even females will fight quite aggressively with each other.
