What health insurance company is best for a child?

I am looking for a good and reasonably priced health insurance provider for my 9 year old son. Insurance through my work is outrageous so I’m looking for an outside provider. His mother is suppose to have already put him on CHIP with the state of TX (by court order) but she refuses to do so for some reason. I hate the idea of him being without health insurance. Anyone had any good experiences with certain companies? Any suggestions or feedback would be greatly appreciated.
