After ages of just using the Zen theme because I thought some day I'd get down 'n dirty with the CSS, I decided that it was foolish to think I'd some day get to build my own theme and picked an off-the-shelf theme from drupal.org. After testing a few different ones I settled on the Sky theme, which is flexible enough for what I need right now, other than a small adjustment to make the site slogan fit underneath the site name rather than pushed down underneath it.
