CSS using borders as menu dividers - except last item

Hi,
I am trying to use css borders as menu dividers (e.g -|) but of course do not want a border on the last item. Menu is an inline list.
See here - http://www.davpatdesigns.com.au/be/
Is there an easy way to do this? I have tried styling the a and li with border-style: none; and also tried a span tag.
Thanks,
Davpat

That’s a winner!
Thanks, thought it should be simple - looks like I’m the one that is simple.
Cheers,

The simplets way is to put a class on the fine LI

<li class=“last”>

#menu li.last {
  border-right: none;
}
