I noticed that it is cheaper to buy two core sets than it is to buy one core set and expansion packs for an additional x-wing and two additional TIE fighters.  Does anyone know if I would be missing anything by doing this?  In other words, is there anything in the expansion packs that I won't get by buying two core sets (pilot cards, upgrades, etc)?

There are pilots and upgrades that are exclusive to the expansions. The expansions cost a bit more, but open the game up more than a second core set, in my opinion. Get three different expansions, though. ;)  And if you like the game and want more ships after that, then think economically and get the second core set. I'm working towards 2 each of all the currently released products. It's a VERY playable mix.

 That's what I needed to know; I'll go for the expansion packs instead of a second Core Set.  Thanks.

i did something similar. started with 2 core sets (more dice and more turn templetes) and have 2 of each available xpansion, except the tie expansion but ill likely get two of those soon as i like having a few more options for upgrades to mix and match with my existing ships and pilots :)

 I definitely think having two core sets is a smart idea since its cheaper than buying the ships separately AND you get some much needed extra dice and tokens. If you could only get one or the other, I guess I'd get the expansions so you have access to all the pilots and upgrades, it just kinda sucks only having 3 attack/evade dice to use since there are many times when you'll need 4.
