Never trust a pet store to gutload for you, petstores are usually 'the enemy'

(bad conditions, bad advice - there are exceptions of course......)
And I'm not sure if he's the owner or not but there's a guy who does the Epic Chameleons stuff on here -

I agree about pet stores, but some actually are trustworthy though. I'm not saying they know a ton about chameleons, but I do trust that they do some gut loading. And like I said I would gut load as well.
For example If I was buying crickets, I would ask what they have been using for gut load and if they were using apples I would make sure I did something like collared greens or bug burger.
Basically, I'm just saying I'd rather get my feeders from a quality reptile store than a chain like Petsmart. The fact that they gut load would just give more variety to my own loading.
Thanks for your concern though. I know I can't just trust my pets with things a pet store says and take it as truth because I know there is a lot of sketchy stores out there.
Back to the housing questions though...
So basically all of my research has came to the consensus that getting the mistking system is the best way to achieve the correct humidity and proper hydration (especially since I won't have time to manually spray the tank since I will be at work from 9-5). I've seen there are a few different systems though. Is the "starter" system any good? It's much cheaper than the rest so I'm a little skeptical, but since I'm only going to get 1 cham I'm hoping it would be enough?
And what do you do for drainage? I'm hoping to slowly start piecing my set up together and would like to make sure the enclosure has good options for drainage and a misting system. I'm thinking about getting a cage bigger than the 4x2x2 but I'm not sure how big yet.
Also, about how much foliage is enough? I've seen cages that are jam packed and I've seen the opposite, tanks with hardly anything. Basically I'm guessing happy medium between the two extremes is best, but what does that look like? If someone could post a picture or link that would be great because I'm still kind of clueless on what the right amount is.
Finally, I've seen pictures of some pretty cool set ups with real plants hanging from the top of the enclosure. Is that a good option or is it better to pot the plants on the bottom? I could see the hanging plants being less stable and have too much swing to them...
Thanks in advance for the responses!
