There are many advantages to spending the money on the full Kontakt version. The ability to add simple scripts to create needs (but you will need to do some learning). For example, even the trumpet in the Factory Selection can be made to sound fairly good by adding the pre written script to make the trumpet monophonic setting the portamento suitably thus creating a simulated legato. There are many things one can do with the full version of Kontakt not possible with the Player version.

Within no time the full version pays for itself when you include the free and cheaper patches.

Also a lot of the Orchestral Synths have there own players. For example, Vienna Instruments Synchron Player for the various VI libraries, Spitfire just to name a couple. Spitfire Labs even has free stuff not requiring Kontakt.
