IB, though the story wasn't the greatest, I do reccomend getting those issues if you can find them for a better price.
It has many flaws, but two great things:
1) amazing Perez art showcasing all the members of both teams.
2) The 'classic' teams acting very heroic, knowing full well of all the terrible things that will happen to them in the future (Hal, Tony as a drunk, Hank hitting Jan, Batman, etc.). Its great to see it as Busiek commenting on the industry: 'even though the creators in the 1980's-1990's decided to crap on these classic characters, they still maintain their heroism and do what's right, knowing full well how awful their lives would become'.
Still...$35 is a bit pricey.
