Constructing a new website, and cant deside if I should use tables or layers to make the layout...

I have a menu on the website that must be positioned with px. With layers I can control the exact position of the other elements, so why should I even think of tables? One thing that comes in mind is the easy way to just set the align center of the table and the web site will be in the middle of the page with no regarding of resulotion or window size... But this also makes problems when positioning the menu that must be set with px....

Give me any feedback with up and downs you have exprienced with layers and tables....
