First off, let me just say that it's easy to lump all Chameleons into the 'hard to care for' bracket - this is true with Senegals, Gracefuls, and Jacksons. One of the biggest reasons for this is that 'most' of them (especially Senegals and Gracefuls) are wild caught and they do very poorly trying to adjust.
Then you've got the Panther and Veiled; I've kept both in the past and currently have a juvenile Veiled. Both of these are widely bred in captivity, and both are 100% easier to keep than a lot of people say.
Now, let me say this: Compared to a Bearded Dragon, or a Leopard Gecko, Veiled and Panthers are significantly harder to keep alive. They definitely require effort, no doubt about it, but they're not 'too' bad.
My current Veiled is housed in a 65gallon Tall Reptarium. He's got a 100w Mega-Ray MVB as a heat source/UVB source. I've got live Ivy and a live Dracaena bush in there for vegetation and humidity (most people underestimate just how much humidity live plants give off).
For water and additional humidity supplement, I have a Little Dripper, that's on a slow 24 hour drip, into the pot of the Dracaena. I also mist his cage three times a day.
He eats a diet of crickets and mealworms.
Sure, it might sound like a lot of work, but it probably takes me less than 10 minutes a day to maintain him. 10 minutes a day is definitely worth the pleasure I get out of him - they have SO much personality, even when they're unable to be handled.
My guy gets handled about once every month or two - they're definitely not a touchy feely type Reptile and excessive handling causes them to stress out. Little Brother comes out for photo ops only.
So, in closing, if you want a fairly easy-to-take-care of Chameleon, go for a Veiled. Very hardy little guys for their species; just not as colorful as a Panther.
If you want a harder-to-care for Chameleon that shows absolutely amazing colors, get a Panther.
I'd recommend either one quite equally, so...it's up to you.
