I have always been hesitant to use any type of automatic watering system with reptiles or rodents. I haven't heard any bad things with misters but plenty of horror stories from massive rodent populations dying to drowning because of automatic watering malfunctions.

Mainbutter, have you heard of anything similar regarding misting systems? If not, a Mistking sounds like an economical way to have a semi hands-free way of keeping the geckos hydrated.
