It is good to be nervous, that just means you really want to take care of your cham. I was nervous as well. Took me six months of planning and research before I decided to take the plunge. It was not as hard as I thought it would be. I did automate by getting a mist king and everything is on timers so really the maintenance is pretty easy with that set up.
Awesome thanks so much everyone. I figure I can afford a chameleon that is 200-250, which I know isn't too easy to find, but you guys have given me great places to keep searching.
for some reason I just can't get away from those nosy be's!! I love that blue!
