Unless you know you need a bunch of splits of the same universe, I'd go with one or two NET-X II. I feel the days of running DMX cable over long distances are over. For the price of running one universe over DMX, you can pull a CAT6 a have thousands of universes. Cat6 probably costs less per foot than DMX now as well.
Switch in the booth, or maybe the dimmer room. Cat 6 to a bunch of locations, drop a Net-X In in/near the foh positions, and another on/above the stage, and distribute from there.
The Net-x are great sACN nodes, and splitters. The only downside would be not being able to configure them from the console like you can with ETC nodes. But that is the same with any console once you leave the manufactures specific product line. The Net-X does have a decent web interface where you can configure and name outputs and load settings, etc. What I don't like about the ETC NET3 nodes, is the inability to configure the outputs locally from the node, you have to use a desk or computer. On the Net-x you can configure it from the front panel.
