I'm surprised no one has mentioned Algebraic Number Fields by Janusz. This is the most down-to-earth book I know which presents a complete proof of the theorems of global class field theory and which is relatively clear and well-written. The beginning of the book describes the basic theory of algebraic number fields, and the book finishes with class field theory. The proofs use a small amount of group cohomology (you should be fine) and use the original, analytic method to prove the First (or Second depending on the author) Fundamental Inequality.

The formulation of the theorems is the more elementary one using ideal theory (as opposed to Childress, which uses ideles). Once you have learned the ideal-theoretic proofs, you might want to read this article. The idele-theoretic versions of the main theorems may be easily derived from the ideal-theoretic ones.

Unlike the book by Cox mentioned above, Janusz's book contains complete proofs of all the theorems. But, as someone who shares your distaste for Cassels-Frohlich, I think Janusz is fairly easy to follow (that doesn't mean the proofs of class field theory are easy, though!).

You also might find this thread to be of some use.
