I'm kind of new to all of this. I've been researching several WP themes, including Thesis & Socrates. I was impressed with how well Thesis seems to be designed & structured for maximum SEO effectiveness. But it's expensive, at least for me.
I found Socrates, which apparently is also well designed for SEO effectiveness (although maybe not quite as well as Thesis) but less expensive than Thesis ... but still pricey.
The Atahualpa theme looks nice & fairly easy to customize. And you can't beat the price - free.

It's hard for me to tell, since I'm not that technical (nor that experienced with IM).
BTW, can anyone recommend a good, not too expensive, Atahualpa tutorial - especially for customizing it with things like banners and the like?
Thanks,
Richard
