Onine church calendar

I was asked to look at online calendars for church this month. I spent a few hours on it and came up with three: Calendars Net, Super Calendar, and Hunt Calendars. The most important thing I think I found is that there wasn't a whole heck of a lot of distinguishing features. To write up a report for the church, I checked prices, and tried to compare ease-of-use and reliability. But I don't think I did it right, because my recommendation actually was questioned because I'd rated the only calendar that wasn't free highest :) Super Calendar costs $20 a year. But I recommended Calendars Net, mostly because it was free and allowed sending reminders for free, the only one of the three that did that. But maybe I missed something...if you know of a better online calendar or a better idea for calendars in general, post it in the comments.
