I can't believe I haven't bought a Lodge dutch oven before this.  We've used them on Boy Scout camping trips for years and just never thought to buy one for ourselves.  Once I read about how it's preseasoned, I had to get one.  I made chili in it recently and it was the best I've ever made.  I was worried about using it on a smooth-top stove but it's not a problem as long as you're careful with it.
