First off, how many will you need? That number should be considered along with how many members/donaters your church has. If I went to a small church, I'd be a little annoyed that my money was buying 15 Rare Earth Blends for the kids who can't hold still in front of a mic. I'd say for your purpose, unless you only need 3 or 4, keep it under $75 a piece.
