I have several low end or older string libs (GPO, the original GOS, NI Session Strings).

Looking for some libs with flexible string harmonics. The ones I have don't really have a full selection of FX that one would hear commonly in Bartok or even a lot of modern movies. (ie presented for 1sts 2nds, Vla, VC, CB)

Suggestions? I can't really afford a -whole- high end lib. I'd prefer 'a la carte' if possible.
