I just recently got a new chameleon after not having one for 5 years. I will break down my total cost thus far.
Also I had a panther as my first chameleon and bought it on a complete whim from craigslist...If you are proactive in learning about the care and willing to provide it, I think you could raise a panther just fine.
Chameleon- $300 Ambilobe Panther
Enclosure XL reptibreeze- $99 on sale at petco
Hood Light- $150 ( I bought a better quality one than I HAD THE HAVE because I wanted it for the plant benefits) You can get a cheap hood and the correct bulb for around $30 and then buy your basking light and bulb for around $15)
Basking fixture- 0 (I already had this)
Supplements- Approx $20-$30 depending on where you buy them. I got mine on amazon for way cheaper and free shipping
Plants/vines- $20-$60 You can go cheap and use fake stuff or get live stuff and make it ebtter for your chameleon and more aesthetically appealing!
Sticks- FREE collect them outside, scrub them, then bake them!
Food- $20-$60 This depends on what you buy. I wanted to start with colonies so it is cheaper for me in the long run and hleathier for my chameleon.
A spray bottle- $1
Total- $730 on the high end and with a panther, a veiled will cost you half as much or less
If you get a mister you're looking closer to $850-900
