There are comparatively docile panthers and aggressive panthers. There are comparatively docile veileds and aggressive veileds. Some people are fortunate enough to have a very laid-back chameleon (Forum member Miss Lily has many posts on her friendly veiled, Tommy, and jannb's veiled pair, Luie and Camille, are friendly; my last panther, Thaxter, appeared to enjoy climbing on me). Many chameleons are less laid-back and would prefer to be left alone. Many chameleons are very enthusiastic about food, especially once they're old enough and have been around you long enough to know that you're the source of food, and not a predator; this can be used to bribe a chameleon to climb on your hand and train them to associate you with good things. It all depends on the chameleon.
Some of the veiled morphs are more expensive than the "regular" veileds (which can be quite handsome as it is). Choose a reputable breeder (the Forum sponsors are reputable; Fauna Classifieds has a Board of Inquiry where you can check on the reputation of other breeders; or Forum members who are not professional breeders will often post chameleons for sale in the classifieds. For the latter, you can look up members' posts in the discussion, photos, breeding, etc. forums and determine whether you'd like to buy a chameleon from them). A picture of the sire/father will often give a decent impression of what the offspring might be expected to look like. An adult or young adult animal will already have much of it's colors and patterns, and you may be lucky enough to find a relatively "tame" one that's being sold by somebody who has to move or for some other reason; by and large, I favor getting them younger and watching them grow up (by three months or older a baby chameleon is well-established and ready to go to a new home; I wouldn't recommend any younger).
