Hi, I am about to start couple of blogs, and as I do not have budget to get a custom theme designed for my blogs (Even I do not know how much will it cost), I decided to go for either a free theme or buy a theme off-the-shelf, and after going through 10-15 respected wordpress themes seller (studiopress, wootheme, themeforest, and through the website of all the commercial theme seller listed on wordpress.org), and twice as many free WordPress theme online directories, I decided to settle down for a semi-free theme.
