These days I am not generally inclined to buy modules, but if the following ones were made I would break down and get them.
Expedition to the Keep on the Borderlands. There's just something fun and slightly silly about the Caves of Chaos. There are also some particularly nasty things hanging around outside the Caves that would be fun to encounter again.
Expedition to the Slave Pits of the Undercity. Okay, you could do the whole Slaver's campaign, but I really liked the original Slave Pits of the Undercity. I ran that module three or four times, it was great. It lead to one of the most memorable encounters of my gaming life. [Quick aside: Freeing the slaves in one area the party asked them all their name and profession. I was rolling Int for all of them and deciding professions from that. I rolled a 3 and said, without hesitation and in the classic cartoon idiot voice "My name is Hey You and I'm a slave." It still cracks that group up and that was in the 1980s!]
I think those, more than anything, would be a "must buy" item for me.
