Events in Django

Being that I am creating a site tightly coupled with events and calendars, I need some event functionality.  There are three options:
  1. Django Basic Apps
  2. Somebody's self-maintained event app 
  3. And ... the event system that's in Pinax

Option 3 really is great.  What a great app written with some really good methods including Periods and Relations.  I'm very excited to use it.
