Invoice format for item quantity

[athena]

Where can I change the format on the invoice for the product quantity? We are using 1.3.0.2 and it currently looks confusing:

1xPaddler Flag

Would prefer something like:

1 Paddler Flag

I think I found the x and just replaced it with  

admin>invoice.php line 158


<td class="dataTableContent" valign="top" align="right">' . $order->products[$i]['qty'] . '&nbsp;x</td>' . "\n" .

changed to:

<td class="dataTableContent" valign="top" align="right">' . $order->products[$i]['qty'] . '&nbsp;&nbsp;</td>' . "\n" .
