The 3 JLA books are some of my favorites. Mainly because as a kid collecting this set, the three local stores that sold comics did not carry that title. It wasn't until a month or so after the books were released that my mom finally took me to a comic shop to get them. And at that point they were way above cover price.
About 10 years ago when I got back into comics, I had an obsession with buying these books. I just couldn't see passing up the books on ebay at such cheap prices compared to when I was a kid. After buying about 40+ of each, the novelty finally wore off.
