I'd be pretty wary of purchasing a chameleon at a Repticon. Most are stuffed into a cage that's overcrowded, and they are extremely stressed. Plus you'll have a lot of breeders looking to make a quick buck by selling them WAY too young. Also, you don't know who picked up a bearded dragon, didn't wash their hands, and then asked to pick up a chameleon. I'd go and look at the sellers, but don't purchase at the convention. Instead, if there's a breeder that impresses you, get their card and then buy later. Just my 2 cents.
