I never really read Avengers much. My kid is Avengers crazy. We're going to Wizard World Chicago this summer and I wanted an Avengers run to try and snag. Any good bronze age story archs I should aim for? I'd like to start a collection for him based on something like a 2-3 year run that wouldn't break the bank. (I buy reader's copies) Any old school Avengers fans help me out here? Maybe a creative team's run, or a guess-timate on issue numbers would be great.
