LLL Reptiles is a site sponsor, and this is a fine kit for starts, but there are gaps and things I'd do different.
18"x18"x36" screen cage - I have a cage this size, then I bought a larger one. I'm now using it for a smaller chameleon, for many this is a size that is fine for a growing chameleon but might too small for an adult.
100 Watt Powersun Bulb - I don't know this bulb, but you will need UVB. For basking, 100W is a lot, a plain 60W in a dome on the top of the screen will probably be plenty (too much if the chameleon can get close).
This is a good all around fixture that has UVB and light for plants, but you would still add to it a plain 60W basking bulb.
ZM Mini Deep Dome Lamp - works great, just like a clamp lamp will, for a 60W basking bulb.
High Range Thermometer - probably a fine inexpensive thermometer. A $25 laser pointer style IR thermometer will give you much better information about basking temp, which is what you want to focus on. Your indoor cage will probably not be too cold (even at night) but the basking location may get too hot, and cause burns.
2 x 72" Tropical Vines - I'd use one for a cage that size, along with a bunch of live pothos or a nice schefflera if I could find one.
Small Jungle Vine - these are good, I'd want a large one of the same as well. Probably some dowels or baked branches too for horizontal basking locations. Dragon Ledges are super helpful for setting up structure inside a cage, and these Jungle Vines are right up there too.
Rep Cal Ultrafine Calcium - you will need additional supplements - most people use two others in addition to a plain calcium like this, calcium with D3 (twice a month) and a multivitamin for a small amount of A (twice a month). Supplements (and gut loading) are really important. I like Pashy Calcium Plus LoD to try to simplify things by making all feedings like another.
Spray Bottle - probably a basic inexpensive one - I'd want to go ahead and get a pressure pump style, like
this one or
this one. Speaking of hydration, chameleons need a lot of water. Consider setting up a drip system (once per second on top of the cage) and maybe even an automatic misting system. Depending on what you do for water and misting (multiple times each and every day without fail) you may want to use a drainage tray, like
this one.
Chameleon Care Book - probably helpful.
Includes shipping - for $200, I'd expect so. But if you're worried about shipping costs, chameleons may not be for you. You can definitely save money by planning and spending carefully, but a lot of time spending less now means spending more later.
