Looking for a Great Dragon's Lair

[JustinAlexander]

I'm looking for a great dragon's lair adventure. I don't particularly care which edition or even game system, but what I do want is a lair that's more than 6 or 7 rooms. (I want the lair itself to be the awesome centerpiece of the adventure.)

Anybody got a suggestion?

Dragon Mountain is a great lair (the "hook" portion is awful and requires serious revision) based on Tucker's Kobolds philosophy. Quickleaf is doing a 4e conversion but you could easily enough ad hoc transcribe it to 3.x/pathfinder as your tastes require.
