I went on my paper tape adventure a few months back picking up a FANUC PPR from eBay. Needed some repair, but they make good units, relatively modular and includes a punch, reader, and printer.
FANUC A13B-0117-B001 is the part number and there are several on eBay right now (one for $400 but listed as a "parts unit"). These CNC resellers on eBay will sometimes take an offer much lower than asking.
