Veileds are considered the easiest of the chams, but no cham is easy compared to most other herps. Chams are nothing like the species you have kept so far. Their caging and climatic requirements are different so you will need to learn alot about how to set one up before you buy. They are not really social pets and won't appreciate handling like many other lizards might. Too much handling equals stress and illness, even death. Play with your beardie, look at the cham. I'll put links to the best cham care websites at the bottom of this message. There is a lot to read, but the info is much better than the typical caresheet. I would basically repeat everything on the sites here anyway, so I'd suggest reading them first and coming back to the forum if you have specific questions. Some of the sites also have books and a checklist of needed supplies and equipment which helps you get set up too. Also, getting a tiny baby will be tempting, but not advisable for newbies. For one thing, many tiny babies just don't thrive. Dealers want to sell them young to save having to feed them. If you get a baby you will need to deal with hundreds of fruit flies or pinhead crix every day, getting baby caging as well as adult caging later, worry about overheating or dehydrating the little one, maybe having to treat a tiny cham for a health problem, etc. Responsible breeders don't sell their babies until they are 3-4 months old. By this time the weaker babies have already gone and you are more likely to get a healthy robust one that can handle beginner mistakes.
