[RPG] What’s a good random dungeon generator for D&D 3.5?

I'm looking for a random dungeon generator for D&D 3.5.

I'd like a generator that looks like Dizzy Dragon's, but specifically for D&D, but also with a theme or groups option (Like crypt, or only undeads – only demons etc).

I've searched quite a bit for a good dungeon generator, but didn't find any especially good.

These are the 'top' ones I've found:

Myth-Weavers – Good, but no random room dressing / themes / encounter types;

Tunnels & Trolls – Quite nice, but too many details, bad maps and not D&D specific;

Dizzy Dragon – Almost perfect, but not D&D specific;

Wizards – Good ideas, but not fully implemented yet (quite buggy in fact) , so half the features don't work.

I'd like to avoid generating anything manually, because of the concept of my game (everything is random, from character races/classes/alignment to adventure ideas).

Note: People say the Donjon one is pretty much what I'm looking for, but the site is offline. If anyone knows another place where that is hosted or a similar generator, I'd be grateful.
