Our repeaters are all under a single radio club and everyone is a team player, so I don't anticipate any political issues.? I was nervous about sharing a single power system among multiple repeaters, but now I am beginning to get more comfortable with the idea.
I am using a 30A Iota power supply in my home station, and I love it.? No more need for a changeover switch and the accompanying voltage drop.? We will definitely need to consider replacing our existing repeater supplies with an Iota supply.
BTW, I once contacted Iota technical support to ask about adjusting the output voltage.? I got very good, prompt support.? The answer was "You can, but it voids the warranty.".? They even sent me instructions on how to do it.
Thanks to everyone for the thoughtful comments and good advice.
