Kontakt is definitely worth it for that price tag. Even more so if you can upgrade it. For one, nearly every major library coming out uses K5 now and for good reason. Anything that can be tempo synched (which lets face it, is basically everything), uses it's awesome time pro feature.
Additionally I have been able to use over 70% of the sounds that comes with it in commercial projects at a satisfactory level of production. The drums (both studio and the african set), is simply gorgeous. The pianos are not too shabby though I haven't used them that much.
Also as mentioned, Damage is a truly grimy epic ton of rape. Totes worth it, grab that too if you can :3
