Studiopress make a variety of Premium Themes (12 at the time of writing). They have a pretty good deal where you can purchase all themes at one price which also comes with the accompanying support.
Their themes are centered on providing sites which are good for a small business. If you are an individual, one option is to use their blog design services after you purchase the theme to tweak it in the way you want.
