Sheesh, it just hit me. I came up with the original ideas for two Kirk Hunter Studios products, Pop/Rock Strings and Easy String Arranger and when Mesh and SmokeyJ628 asked about PRS, I completely forget to mention that Pop/Rock Strings now includes Easy String Arranger (as does Concert Strings 2)! So, in addition to the strings sounding different than Diamond, another reason you might consider PRS is Easy String Arranger -- which is a really cool tool that helps making string arranging for those without formal training arranging strings and for those who do have formal training, it just makes it easier/faster to get ideas down when inspiration strikes. I'd still say that, if you have the budget, Concert Strings 2 is ideal (PRS is a subset of the CS2 library, with less samples per octave and less articulations). But if CS2 is out of your budget, at $89.50 USD, Pop/Rock Strings gets you different sounding strings you can blend with Diamond and Easy String Arranger (here's the info on it:

For $89.50 USD, you don't need to own the full version of KONTAKT (it's compatible with the free player), contains both solo strings and string sections and very sophisticated scripting (which, imo, makes a giant difference in string libraries, especially to those who've been using sample libraries from the days of dozens of patches and trackzillas) plus Easy String Arranger, which I think sells for $29 USD on its own normally. There's nothing on the market even remotely close to the price (I know, I did the original research and still pay attention to the string sample library market pretty carefully).
