Router Head
I used a Porter Cable 690 router head, because I already had one. You can buy this router head alone, or as part of a router kit. See:
To mount the router, I used this K2CNC mount: RM-PC892. The FineLine Automation z-axis plate (CRP140-01) has mounting holes pre-drilled and tapped to work with K2CNC router head mounts.
