Cinematic Strings($499.00) or Adagio by 8Dio(Introduction Price: $399 ($599))
I can't speak from personal experience on either of these, but going from the demos, Adagio sounds (to me at least) cheap and synthetic compared to Cinematic Strings. Cinematic Strings sound warmer and more lush -- I don't know if that's what you're looking for, though. Also, both seem to have reverb built-in to the samples: while it's nice for getting a quick and easy sound going, I found with EastWest's Symphonic Orchestra (which was also recorded in a hall) that the natural reverb on the samples actually got really annoying to work with, and sometimes clashed with other libraries.
If you're going to really do some serious string part writing, I'd truly recommend saving up for L.A. Scoring Strings. It's pretty damn expensive (about $1000 for the whole thing; but they do sell sections individually, and you can upgrade on a dollar-for-dollar path), but it has a versatility and flexibility I haven't seen matched by any other libraries. All of the samples were recorded on a sound stage, so there's little to no reverb on the actual samples (so you can add whatever want, and it won't sound too mushy). Even their solo strings sound fantastic, I'd say it sounds a lot better than the new EastWest Solo Violin.
Symphobia & Symphobia 2 (about $1300 each) are also very nice libraries. They focus less on solo instruments, and instead just go for big, epic ensembles -- full strings, full brass, full woodwinds, combined strings & brass, rises and effects, etc.
...I'm sorry, I tend to get a bit overexcited for sound libraries. And usually end up spending way more than I can easily afford!
