This is a sensitive topic to most. I personally don't like downloadable themes and always suggest people build their own. I just find it tacky to go to a website and see the same theme on that website on other websites. You'd probably disagree with me. But I'm sure if you had the knowledge to build and design your own themes you would probably prefer it that way. I noticed a co-worker of mine looking for Drupal themes. After a friend of his sold him the idea of creating a Drupal website for his band, he began researching. He already built his band website entirely in Dreamweaver (It's a piece of shit) and rather than admitting he's not capable of building his own theme, he just says he simply doesn't have time to build his own theme. I'm sure I struck a couple nerves there.
