For any of you, who like me, are frustrated with OF's very basic repeating options, and lack of tags, etc., you might want to check out ToDo by Appigo.
They have a trial version on their site.

They have much better repeat functionality and a more streamlined interface (although I haven't worked with it enough to see if its *too* limited).
No event/iCal syncing yet - but perhaps they'll be more open to suggestions!
'not affiliated with them in any way, just came across it today and it looks interesting!
