Auctioneer Site (not updated) FuBar on WoWAce (doesn't seem updated) ElkBuffBars on WoWAce (IS UPDATED) WoWAce only has Ace Addons (obviously) but they're always the most up-to-date versions, from what I see, which makes it great for AddOns that are updated REALLY regularly. It also has some Ace AddOns that can't be found elsewhere AFAIK (generally unstable betas)
FuBar and ElkBuffBars are both updatable through the
WoWAceUpdater, too.
Hope ClassTimers is still working, EBB bugged out on me long ago and now I don't trust it.
Has your "Load out of date AddOns" accidentally come unchecked for some reason? That happened to me with 2.4, not been able to log in yet to see if it's happened again.
