There is a promotion going right now in which you can get a free version of EastWest's renowned Symphonic Orchestra plugin after filling out a painless survey. Weighing in at around a gig and a half, I'm sure it's heavily gimped compared to the retail versions, but hey, it's EWQLSO for free! It doesn't expire, and there's also mention of a discount on the retail versions until near the end of the month.
EastWest/Quantum Leap Symphonic Orchestra Starter Edition
Sweet, thanks for the tip.
