In the summer of 2007, I had just finished paying off my last credit card (and haven't carried a balance since!) and, with my wife out of town summering with law firms here and there, I have a few extra dollars in my pocket for the first time in a while. I actually got back into comic books for a (very) short time. I was smarter about it than I was my youth: This time I only bought stuff I knew I was going to enjoy. So I got back into the classic characters. Here are the "big three" of DC Comics.
About a month later, I would discover that I was a daddy, so I stopped spending the $15/week on comic books and eventually even gave almost my entire collection to the local Goodwill, though I kept a few gems. These days, I wait until the collected editions come out and get only the ones that are well-reviewed.
