I had one years ago, and they are a blast, fun just to watch eat and walk around.

Very good website for a reptarium cage, black pvc inside for the frame, and then the mesh outside with zippers on the sides to access things, never had issues with crickets escaping or anything.
Also you can order bulk crickets and keep them in a spare cage in maybe a garage as so you dont have to hear them all the time, just toss some cricket food in there to keep them healthy and alive, and easy to make the feedings for the cham. rather then a drive to a pet store often.
Bulbs like others are saying are very important, overtime with out bulbs they will start getting brown and not change very many colors anymore, and it hurts there health and so on.
I had a waterfall rock structure for running water use, he would climb it as well as drink from it, but misting plants is a big plus and important as well, give them lots of choices they can be picky.
