Any good GM can convert between D20 rulesets, and stripping D&D 3e stats out of adventures and settings to use with the OSR ruleset of your choice should be trivial.

Of course, I offer some Tavern Picks:
Dungeon Crawl Classics #51: Castle Whiterock - Castle Whiterock is a complete campaign. This box holds more than 700 pages of material, enough to take new characters to 15th level and fuel a campaign for years. It contains:
Four books detailing the dungeon’s 15 levels and 14 sub-levels, colored according to level: red book, blue book, green book, and black book. Every map location is fully described with stats included.
A 56-page gazetteer of the Kingdom of Morrain, including the town of Cillamar. A 48-page book of maps. A 32-page book of player handouts. A poster map showing Cillamar on one side and the final two levels of the dungeon on the reverse. Six loose-leaf character sheets of the pre-generated heroes, ready to play out of the box, plus one blank character sheet to copy for later use. A 16-page index and glossary.
Dungeon Crawl Classics #35: Gazetteer of the Known Realms - Certain adventures only come around once. Like when the grizzled old warrior decides to go after the dragon, and asks who’s coming with him. Or when the dark-eyed sorceress slowly surveys the crowd of peasants, waiting for one to step forward and pull the sword from the stone. This boxed set contains those adventures. Dungeon Crawl Classics #35: Gazetteer of the Known Realms brings together the Dungeon Crawl Classics modules into one comprehensive world. This magnificent set includes: Gazetteer of the Known Realms, a 120-page book describing the archetypal fantasy world of Áereth. Three 24"x36" poster-sized full-color maps of Áereth ready to host your adventures. GM’s Guide to the Known Realms, a 136-page sourcebook describing deities, equipment, creatures, and NPCs, plus rules for starting campaigns with 0-level characters and adventure paths that you can build from existing DCC modules. A 24"x36" poster-sized players’ map of Áereth. Halls of the Minotaur, a 32-page adventure module for 0-level characters perfectly suited to starting off your campaign in Áereth. The Thief Lord’s Vault, a 32-page adventure module for levels 4-6 that sends the heroes into the legendary treasure vault of Cazül the Chaotic.
Dungeon Crawl Classics #48: The Adventure Continues - Remember the good old days, when adventures were underground, NPCs were there to be killed, and the finale of every dungeon was the dragon on the 20th level?
