Realistic strings

So I'm new to creating music on this app. I went around and looked up the best ways to do the best sounds. I came across a plugin called SWAM. I did however see that the string instrumental package alone cost $500.

My question is, is this price tag worth the sounds it creates? I'm looking for the most realistic, and want to know if this really is it or if it's a scam or something. I have the money, just need to know if it's real or not.
