I'm loving Castle Zagyg: Yggsburgh by Gygax himself, still available and only $24 on amazon.com - Amazon.com: Used and New: Castle Zagyg Volume One: Yggsburgh
It's a wonderful full sandbox campaign, brimming with countless adventures, plot hooks, encounter generators & encounter tables, all kinds of stuff. If it wasn't for the link to and non-appearance of the actual Castle Zagyg I think it'd be regarded as a real classic.
It has C&C stats, which convert to AD&D/OSRIC/LL et al simply by flipping the AC from ascending to descending. It does have some editing issues and requires active reading - eg you need to decide for yourself if listed gp values make sense for your campaign, I typically divide them by 10. But overall the structure is actually very good IMO.
