Hi - glad you are inquiring before buying - many people don't. If you are looking for a herp that you can handle I think bearded dragons are best (I don't have any, but it is what I hear). Chams in general are not touchy-feely critters at all. They are also high maintenance. I have linked you to an article on cost, requirements, etc.
There are also a few sites that we (forum posters) highly recommend. If after you read up on these and other responses to your initial question you still think you want one please feel free to continue to ask. This is by far one of the friendliest and helpful forums on the subject (and ACTIVE- whew!). I found them a year ago and never left
