I personally like it. It's definitely what the Borderworlds Bomber should look like - an extension of the previous model.
As for people saying 'it's just a Sabre with stuff on it', why nobody whined about the Roc ? Isn't it just an upscale version of the Eagle? It's a tiny tad bigger, and has two top fins, instead of one, two more engines and the torpedo tubes. But that's about it, and people like it.
Also, I would like to mention that you people need to read the Borderworld Ships infocards. There's nowhere to be said that the Sabre, Stiletto or Dagger are made by outcasts and distributed to whichever factions. They're probably made by various corporations and factions, bearing the same blueprints.
