Hard for people to say they want to stay if they don't know what it is going to cost. And "affordable" will mean very different things to different people. But I understand needing to know how many before nailing it down.
So, can you give us a ball park? You've heard from several of us that we want to be moved to the server that is to stay, so can you tally those requests up and say "That's X at present and if we get no more it'll cost $Y/mo. But if we can get it up to Z it'll be about this much."
