If the story is simple enough, and is found in one passage, we usually just read to our children right out of our Bible.
However, sometimes illustrated storybooks are nice. We use A Child's Garden of Bible Stories by Arthur W. Gross and The Golden Children's Bible. And of course, Arch Books. I have fond memories of reading The Bible Story series by Arthur Maxwell, but I cannot attest to their orthodoxy (I should dig them up at my parents' house and write a review...) What do you like?
