Heh. I just stick with the Science Diet stuff, because I know it's good quality and isn't quite as obnoxiously priced as some of the others. I figure if the vets carry it (it's usually either the Hills stuff or the Purina stuff), it's got to be at least passable, and it's already been studied to death (unlike some of the other stuff on the market now, which is more 'claims' than science, if that makes sense).
