If you want the proper set up, it will cost you anywhere from $600-$900, including the chameleon. I bought my guy at one year, and he was $150. You can get babies online from anywhere to $40-$70. Pet stores will rip you off and don't care properly for their animals--look for a breeder, or a reliable reptile store.
Sunglass frames are made from metal or plastic. Metal frames, particularly expensive ones, are often made of mixtures of nickel and other metals such as silver. These frames have precisely engineered features, such as sculpted and gimbaled nose-pads, durable hinges with self-locking screws, and flexible temples.
However, the lightness and stiffness of aluminum in some eye glasses designs offers great advantages. For example, for metal frames that are thicker in design, and larger in design, aluminum is the toughest material and can accommodate the thickest and heaviest lenses. Aluminum frames last a long time and can take a lot of abuse compared to plastic frames, or thin metal frames.
