Depending on your budget and your preference for a resistor-based or transformer-based passive you may want to consider:
Goldpoint
Space Tech Labs
Welborne Labs
Electra Print
All of the above will let you have as many inputs and outputs that you require. I just recently went through this process and in addition to those above, looked into the Placette, Reference Line, Luminous, and Bent Audio. In the end I decided to have a TVC built for me by Kevin Carter at K&K Audio that uses S&B transformers. This will run higher in cost than those you listed and some of those I mentioned, but Kevin's work is great.
