Somewhat notable is an attempt to make a B/X version of 5e. I don't like 5e much, but might be worth a look if you do
Tegel Manor - Judges Map - Okay, not from TSR, but still an official product. $2 for a map of the infamous manor.
Dungeon Full of Monsters, 2nd Edition - Although aware of the original version of this, I have never heard anyone talk about it, anywhere. It's a large megadungeon for Labyrinth Lord, from Red Box Vancouver who has put out some decent stuff. But at $20, I'll keep wondering about it. 198 pages.
The Dachshund Dungeon - I don't even know where to begin. 8 pages, PWYW
The Idola of Bala - Actually only Idol, but it's a funny typo so I will leave it. Short, 2-3 level adventure for Odysseys & Overlords. $1, 11 pages
Vigilante City: Die Demogorgon Die - Very small, 2 page adventure for the OSR superhero game. $2. That's almost as expensive as Frog God products on a per page level
Kuf - Seems like an OSR version of Kult. (As an actual Gnostic, which I stumbled into in my college days, I find games based on it very puzzling. I wonder if there are any games based on Hare Krishnaism? Jews for Jesus?)
The Marshal - ? New class, I guess military, not law enforcement. 1 page, PWYW
Friday Enhanced Map 5-17-19 - Looks like an underground chapel. $1
