spyderman Its nice the breeder gave you that opportunity but by "looking elsewhere" if someone refuses it you are alienating yourself from some of the best breeders in the world. Most people just simply won't allow it and it has nothing to do with being shady.
Not trying to change your mind, but basically I would almost trust someone MORE if they didn't show every single person they meet their collection. It says something about what they want out of their reptiles if you ask me. But thats just me, IMHO.
