Why sell it? Why not send it on a noble Crusade and either blow up some planets, send it as a distraction, act like you're going to blow up all of their planets(bluff), blow up some capital ships (if you can), slaughter countless numbers of Rebel fighters that are trying to get past lots of Lancer Frigates and the like to get to the Death Star. I'm even going to be the Rebels, and I can come up with a lot of fun uses for the Death Star. I MAKE TACTICS FUN! Yay!
