I currently use Elegant Theme's "Glow" for http://techhaze.com, which I'm not 100% satisfied with.
Elegant Themes makes the .psd file of the theme available upon purchase, which gave me the idea of trying to customize it to my needs.
Here is what I've come up with: http://techhaze.com/wp-content/uploads/2010/01/TechHaze.jpg
As you can see it's mostly color changes, nothing too complicated really.
For the one willing to help, I'd provide the .psd file + the whole theme folder.
I guess it's just a matter of replacing the right graphic files and taking care of the gradient background in the CSS, but the .psd structure is a mess and I don't really have time for guesswork.
Anyway, if you're interested or have advice, drop me a line!
