Are the BestBuy steelbooks for the other Die Hards worth it for someone who doesn't already own them on DVD? I was tempted to pick up that really cheap box set that came out when Live Free hit theaters, but it seemed really lacking when compared to the previous trilogy release, so I always put it off until I picked up that one. Now BestBuy has these steelbooks which I guess are two discs, but of what? Is it just the latest single disc re-releases with an extra BestBuy exclusive or are these the actual previous special editions bound in steelbooks?
