Johnny Stewart digital sound modules

Any predator hunters out there want to get rid of old sound modules for Johnny Stewart Preymaster?  As I understand these calls are out of date technology-wise.  This is the model I have so it's where I'm going to start.  Right now I have Coyote #1, #4, and General Predator #1.  Looking for more variety that have coyote hunting in mind.
