If you do go for an Intex SWCG, be aware that it may include a copper ionizer feature. This feature puts copper ions in the pool water - something that's not very popular around here.

Copper can stain the pool, fingernails, and light colored hair (lightened and colored as well) green. It also has the somewhat dubious effect of supressing algae without killing bacteria. In other words, the copper can help a pool look clean while allowing bacteria to pass between swimmers (or from below the waist of a swimmer to above the neck - yuck!). Perhaps there's a way to defeat this feature.
