I've bought a couple guitars online now, one custom and one from a place called mojo music. Both came packed really well, in a case in a box. No issues at all so imagine sweetwater would be as good or better.
What worries me about Bungie and Destiny's future is they are now free of Activision yet just got a $100 million investment from NetEase, who is also making the diablo mobile game, for an unannounced Bungie game.
