I agree, Chameleons aren't a beginner pet. My first reptile was a chameleon but I'd spent about 3 years learning, preparing, and asking questions to those I knew had gone through it and I am doing okay.
You have to know what you're getting into and know they are high maintenance and aren't a handling type of pet. Also, make sure you get the chameleon from a repeatable breeder. AVOID wild caught specimens as best you can.
Learn and prepare and decide on what you can afford and how much time you can invest into this reptile.
