Yeah. You're best bet is to look for a library that fits both your musical style and your budget.
Good arrangements are key. For the most realistic tone it's also often better to manipulate the notes dynamics and duration as well as using controls or key switching to change articulations... If appropriate.
East West, 8dio, Spitfire, Cinesamples, IK has a new release, then there libraries at Native Instruments.
Look around, check out the vids and reviews on YouTube and see what you think.
