    I prefer, generally, to not use the > event. I think it's cleaner to keep behavior separated from content as much as possible.

    That said, there are occasions (usually pretty rare for me) where using body onload can give a slight speed boost.

    I like to use Prototype so I generally put something like this in the > of my page:

    document.observe("dom:loaded", function(){
  alert('The DOM is loaded!');
});

    or

    Event.observe(window, 'load', function(){
  alert('Window onload');
});

    The above are tricks I learned here. I'm very fond of the concept of attach event handlers outside of the HTML.

    (Edit to correct spelling mistake in code.)
