Javascript Marquee to replace <marquee> tags

Question

I'm hopeless at Javascript. This is what I have:

<script type="text/javascript">
function beginrefresh(){
var marquee=document.getElementById("marquee_text");//set the id of the target object
if(marquee.scrollLeft>=marquee.scrollWidth-parseInt(marquee.style.width))marquee.scrollLeft=0;
marquee.scrollLeft+=1;
setTimeout("beginrefresh()",10);//set the delay (ms), bigger delay, slower movement
}
</script>

It scrolls to the left but I need it to repeat relatively seamlessly. At the moment it just jumps back to the beginning. It might not be possible the way I've done it, if not, anyone have a better method?
