I got my chameleon through the Screameleons ultimate set up package. It's great. Vincent and Farrah are great and their chameleons some of the best. I definitely recommend their set up.
This being said, chameleons are expensive. The kit was around $500-600 with baby male Ambanja chameleon. I have easily spent an additional $800 if not $1000 on my chameleon in the past 8 months. People who are experienced with chameleons will spend much less than that, but they already have all the equipment or have time and resources to build their own. Feeders can get pricey if you want variety, which is what chameleons require.
The ultimate set up is only good until the chameleon turns 5-6 months. By then he'll be too big. Then you'll have to get a cage that is 4 ft high, 2 ft wide and 2 ft deep. You can't go smaller as chams get over a foot long. You can, of course, go as big as you want
This is my first chameleon, but I spent months researching and have already kept reptiles and amphibians in the past. A chameleon is NOT a begginer lizard. It's like having a child, except this child has to eat live food.
If you are prepared to spend a huge amount of time taking care of this animal and are capable of buying what it needs as it grows older, then GO FOR IT! You won't regret it.
But if money is an issue, or you are not sure, then I would reconsider. These are very high maintenance animals that require a lot of love and (unfortunately) $$$. Investing over $1000 in one chameleon over just a year is not crazy. My cham doesn't live in Monaco. But if I need to drop $200 (vet, etc) for him, I won't think twice. You have to be able to do that. I'm finding that once you get all the adult equipment and feeders all set up and figured out, it's actually not very expensive at all every month. I spend around $60-70 on silkworms and hornworms a month. I have 3 different types of roaches breeding and other feeders that I breed myself. It's not a lot. You can't just buy crickets or roaches to feed a chameleon. You get crickets/roaches AND other feeders.
If you have any questions about the Ultimate set up, feel free to pm me.
If I totally misread your comment and you know everything I just said already, then my apologies for wasting your time :P
I have a bad habit of writing too much on these posts, but i really want you to know what your getting into. Getting a chameleon is not a toy. It's adopting a new member of the family.
