I have both Befaco Out and Ferry and like them both. Yes, you can use Ferry's send as an output, or as Jim says above, just use your mixer or passive attenuators. But it is handy to have each of these modules. The 1/4" balanced outs/headphone and the cue feature on Out are all useful, while with Ferry you have to use adapter cables, but that lets Ferry be quite small. For the space these take up, the convenience wins for me. You have a number of much larger modules, and you might think carefully about each of those.
