(This blog post is bit technical and is meant for people who are using wordpress for website development or blog.)
The name is bit awkward to pronounce, atahualpa, but it is the most convenient theme I have seen in terms of customization for your needs. You can configure almost every option through the menu driven options page. No more wrestling directly with css/php files in theme editor. Bonus: SEO tools are also built into it.
It is free but hurry up. Author may change his mind and put a price tag on it. 🙂
