The first TPB of this comic is out. If you wait to buy the compilations, now's the time. The other titles in the rebirth event are issuing TPBs, too. I've read most of the comics at my dad's because I'm collecting only Superman, Action and Batman, the latter mainly for Bruce's relationship with HIS son. I'll wait for the trades to go to auction on Ebay before getting Flash, Green Lantern, WW, etc.
