A while back I bought the box set on blu ray for $49 at Best Buy. It's basically the dvd sets transferred over to blu, there's nothing new extras wise in the individual seasons, but for 50 bucks I couldn't pass that up. I still see it at that price every once in a while, might be worth it to keep an eye out. The 10th of January marks the 20 year anniversary of the show's premiere. That seems crazy. I remember watching this show with the same group of friends every Sunday, was definitely an event. I even managed to see the season premiere of "Two Tonys" at a local cinema.
