well..
if you look around and see the sires and what type of chameleon you want coloration wise, ect. then thats the best place to buy your chams, i got mine from mike at fl chams as i liked the breeders he had. and i wanted a red cham, not only did i get my red cham but i got lots of support and a very helpful attitude there. What excactly is the most important thing you want when buying your cham? type, color, size? once you have an idea then you start shopping. all the guys who advertise on here are very reputable and safe as far as healthy chameleons go. if you buy from a private breeder be sure you know of him through some means cause you may not know what your getting.
