I am starting a new campaign in a few weeks, once Shackled City is finished. The plan right now is to start with Wizard's Amulet (Necromancer Games), then follow that with Crucible of Freya, then possibly The Dragonfiend Pact (DCC 11), then go to Tomb of Abysthor and Rappan Athuk.
The home city for the PC's will be Bard's Gate, and I will probably have them hop between adventures in Tomb of Abysthor and Rappan Athuk. They would probably get bored if they just had to go through the entire dungeon all at once.
I have other stuff I want to use later on, but I figure that plan should get them to lvl 10 or so.
One more thing; if you are DMing for new players, try running The Wizard's Amulet, and have that lead in to Crucible of Freya. I know time is short, and I'm not sure if you have CoF, but WA is available for free as a PDF at the Necromancer Games website. Although I also think that The Adventure Begins is a great starter, so use whatever you have on hand, I suppose.
