I've got a 530 GPH pump, a timer, and a nozzle used to water plants. It definitely creates "rain," and the chameleon drinks from it just fine, but it dumps alot of water on the bottom of my cage. After the pump, the timer, the nozzles, tubing, and fittings I was well over $30, but not nearly as much as the misting systems with the high pressure pumps. What everyone needs to remember, though, is that you will not be able to create enough pressure to run a fine mist nozzle with these cheaper pumps. You need to get a nozzle with either very coarse mist, or more of a sprayer/dripper. And with these nozzles you get a high flow rate which means you need to have a very good drainage system.
