Let me just make sure I've got the way Replicator is supposed to work correct:
Turn 1 (or so):
No Replicators installed. I install a Replicator, which allows me to search my stack for another Replicator and add it to my grip.
Later:
2 Replicators installed. I install a Cyberfeeder (or whatever); the Replicators allow me to search my stack for up to 2 more Cyberfeeders and add them to my grip.
All good?
