I like this site http://www.xxlmag.com/ I would love my site to work like that, with 12 categories, site search, directories, ect.. Basically the way it works and handles, thank you.
Are you looking for a free one or paid ? For free you could modify this one : http://justintadlock.com/archives/2008/02/24/options-wordpress-theme For paid you have the ones at : http://www.revolutiontheme.com/
You'll find plenty here themeforest.net/category/wordpress/blog-magazine Just pick the style you like
The http://www.revolutiontheme.com/ theme is ok but the themes at http://www.solostream.com/ are better in my opinion.
check out "new wp themes" and select "magazines" - they have loads to download for free hope that helps!
