single column, drop down menus, customizable template

Hi,

I am new to wordpress and blogs and for the past few days now I have been scouring the web looking for customizable wordpress templates that have 2 main features.

1. A single column (i want to include large images in my blog)
2. drop down menus for navigating to archives, categories etc.

I like the clean look of a blog without any sidebars.

I will need to be able to customize the width, colors etc.

Does anyone have any ideas/recommendations for such a theme?

Thanks
