foggers are not necessary and only really provide a nice aesthetics. Get a mist king by whatever means possible. Trust me I've made the rounds with the other cheaper misters and none compare. Buy one online as it's probably the only way to get one anyways...
Misting for all chams. Foggers seem to be best suited for montane species. I have used a fogger with veils before. Really, you just need to make sure your cham is hydrated. Make sure it's pee is white and not orange. Personal choice.
