Remodeling and shower heads

I've read the previous discussion on shower heads but I don't think it answered my question. I am remodeling "my husbands" bathroom. My bathroom has the shower head that flips apart. I do like it but I'm looking for a typical shower head in this bathroom. Now that the shower is being redone, I might just use it. I saw mention of a study that rates shower heads but didn't see the link. Does anybody have a suggestion? My contractor just said buy American.
