The cage idea sounds good, but why spend the extra money on a small cage to start with?
If your choice of chameleon is a great deal based on if you can handle it, then I would not get a young chameleon, their personalities change as they mature. If you want to chance having a nasty chameleon when it matures then I would recomend a panther, they are more likely to be calmer than a veiled, but ever chameleon has its own personality so its a 50/50 chance with a juvi cham. ( I had a male panther that I could not stick my hand in the cage without him charging at me open mouthed, the others I can handle, they are not happy with it, but they are ok. in the same respect my male veiled was the sweetest thing ever even at a year old he would climb right on me when I opened the cage and look around for food, then I bred him and he hisses when I walk by.)
In general panthers have a better disposition and require a little less humidity and heat than veileds. they are more colorful, but veileds are practicaly indestructable, and their casque is just so neat
all up to you on how much you want to spend and what you like.
Again welcome and thank you for doing research first. if you have any questions including what you might think are stupid ones feel free to ask, there are many of us here very happy to help out.
