and dude, if you know how to use torrents... I definitely recommend steinberg's hypersonic 2.
It's probably my most used VST besides the minimoog emulator I have.
Basically, it's a professional quality software synth, but the shit it has is awesome and sounds more realistic than any free VST would (even though this would be free if you downloaded it via torrent).
