Elexio are the most expensive option on this list (starting at $500 one time fee plus $60 per month, up to $295 per month).
Their target are mainly big established churches and for the price they will deliver an excellent product and support. Even at the high price, their lower plans are quite limited, with only 20 pages and one form allowed for the $60/month version. This is the main reason their rating is low, but if your church can handle the (relative) high fees, definitely give them a try.
Before you do be advised that they require all their clients to adhere to the National Association of Evangelicals statement of faith, contact them for more info on that.
