I skimmed through the replies and, eh, time for an unpopular opinion:
If you can't spend some money on supplies, don't spend money on a chameleon.
If you think spending $350 is out of the question, wait until you get a $200+ vet bill for something you may not expect or some odd accident happens.
However, this doesn't mean you can't get supplies for less than $350.
Save up $350 for a vet bill. No, don't go buy the chameleon and cage with this. Then, save up more money and browse craigslist for a while.
I've gotten a whole cage setup for $50 (less UVB bulbs, won't buy those used). Patience is key.
