Just to clarify...
Revenge of the Giants is not the Against the Giants series updated to 4E. It's a completely original 4E adventure that was inspired by the AtG series.
Thanks for the clarification.
Although I could see room for both in my - imaginary - classic series

There are tonnes of great mod's that I never got to run. I could always try run them in 1e as Mr Gygax intended, but I'd have a hard time prying my players away from their Character Builders.
There are a few newer 2e mods and even some classic 3e ones - Sunless Citadel I'm looking at you - that I would consider. Or the Gates of Firestorm keep from 2e.
