What's a good theme for my site?

I currently have the "bizine" theme on it, but instead of that wasted space with sponsor ads (that doesn't seem to work for some reason), I want to add in banner space so that I can fit 5-6 small banners on the page. The main reason is because although my conversions and epc is low, I have way less impressions then clicks..so I wanna get the banners on my fake WH site.

Have you tried thesis? I love it because it's so clean and easily configurable (in the options of use "hooks" for even more customization). You can download it from the download section.
