DC or AC to run the Ham Station?

I have built a new Ham Station and have a 12v DC battery backup system. I have posted details of this system in the past. The big question now is do I run it on 12v and let the charger keep the batteries charged or run it from 110vac using transformers to get 12v? I have seen pros and cons both ways. The batteries are on the other side of the wall next to the operating position so the leads would be short. I have also been looking at some DC lighting. I am looking for ideas.
