I agree with JD. I picked up a Star Wars Premium at that same show and absolutely LOVE it. I have access to a BM 66 via my friend and have played hundreds of games on it. BM66 is a much longer playing game and the rules are getting really good. The 1.0 code on Star Wars is fantastic and I can't stop hitting the start button sometimes. I really don't think you can go wrong with either. I wouldn't have said that 90 days ago as BM66 is finally starting to show the promise everyone thought it had over a year ago.
I would get the one that you gravitate towards theme wise.
