What Would Be A Good Sound Library To Get - Suggestions Please?

Hello!

I'm using Sibelius 5 on a Mac and I really want to get a good sound library. I hate the Kontakt sounds that came with Sibelius so I always use the default sound library, which is actually pretty good, but it's far from ideal. Has anyone got any suggestions about good sound libraries? Ideally I'd like something with a really good percussion section ;)

I also have no idea of the sort of price range of these things, so it'd be great if somebody could give me an idea of that as well :)

hm....Vienna Symphonic Library?, I don't know much about it, but I do know John Mackey uses it. http://vsl.co.at/

Upgrade to Sibelius 7.
