Is it just a design issue? The paid one's are prettier, and easier to customize?
I can handle css, and don't mind tinkering under the bonnet, so, is it best to go with a free theme?
Is there something I'm missing about a paid for theme? I'm reading up on the Thesis theme, it says it's more of a framework.... ok.... is it worth the hefty price tag? or should I just use a free theme for now... and come back to it later? I assume it's easy enough to change your theme?
