misting systems aren't especially expensive, unless you go with copper tubing....
the "technology" is most effective in areas with low humidity. Las Vegas, for example. most establishments with outdoor areas have misting systems - and they are effective - it'll be 10-15 degrees cooler inside the "mist envelop"
it's the same theory as "swamp coolers" - areas where the humidity is an issue seldom benefit. my son had a huge free standing swamp cooler for his shop in VA - the fan was nice but temperature wise it did not do much. he sold it.
