Ive got to toss in my vote for Wizards Amulet here. It rocks and the price is right (free!). It also requires little to no conversion. Add this to the fact that it is a straight seguay into the extremely fire Crucible of Freya and you have something that will potentially provide you with many hours of fun.
Check out "Of Sound Mind" from Fiery Dragon. It is 3.0, but I just ignored it and used the stat blocks as they were when I DM'd it (in fact I think it would be a little tough if properly converted). It's pretty well written and has some great scenes in it. My group liked it a lot and as a DM aside from 1 thing I thought it was good.
I also want to mention that "The RPG or Supplement Most Likely to Inspire Good Roleplaying" The Hamlet of Thumble is now on sale for GM's Day at $7.99 (from $14.99) along with a lot of other great stuff at Indie Press Revolution. That's from Feb. 25 to Mar. 11.
And you get FREE shipping on orders of $25 or more.
