Best Third-Party Adventures

[Cubed]

There are some four and five star GMs in my area who have played for years and are running out of PFS adventures to play. Do you have any recommendations for a third-party adventure that would be no more than six hours?

Thanks!

The excellent stuff is usually long.

I know wotc wrote a bunch of free oneshots of about that length for 3.5e, those might still be up on the archieves, or could be dug up with some google-fu.
