Please realize that when my post said every one that it was a bit tongue in cheek. But many estimates put the number 70% on the proportion.
Urban churches are more likely, but honestly once I used to live in a very small county in rural Appalachia, with no cities, or even large towns. And even there the organists were homosexuals. In fact, they were the only ones in the county that I knew to be that way.
But, yes, not all church organists are homosexual!
I don't know much about the current organ scene, but I would recommend against a real pipe organ unless your church has deep pockets and the willingness to make a long term commitment. They require a lot of maintenance, and are very sensitive to environmental conditions such as temperature and humidity. For this reason many churches have an organ tuner come out every month, if not once a week.
Modern electronic organs are acceptable if the goal is to accompany the hymns, and praise God. The names you mentioned are well known and well respected. You would need to investigate their long term reliability and maintenance.
