Julian, I work at Körber Digital (part of the bigger Körber Group, which does manufacturing machines of all sorts). The Rockwells I have are "on lease" from the other group companies, they are the same exact models they use in their big paper, tobacco, palletising, ... machines.
Sorry but I really have no idea where to get them, or how much they cost...
