The second death Star was a very bad idea and i agree with Kasden on that one. If the budget was not an issue the duel would have been on the imperial home world in the emporers court on Had Abbadon, coruscant was a 90's EU creation
I'm glad this idea did not prevail, largely because the name "Had Abbadon" is really, really stupid. It's almost as bad as Elan Sleazebaggano.
I didn't really have a problem with the second Death Star. The thing destroys planets - why wouldn't the Empire want one?
