I did look and the code I pulled is directly from your site.  In your 
/html/html-templates/productPage.inc file you have a border=1 set.
Look at line 7...within a line or two depending on how your editor brings it up.
The first several lines of that file look like this:
<!--agorascript-pre
{
local ($myans)="";
if ($rowCount == (1+$minCount)) { #first one
  $ags_row_item=0;
  $ags_tot_item=0;
  $myans .= '<tr><td colspan=3>
<table width="100%" border=1>'."\n";
I don't see anyplace else that could be causing it.  LMK how it goes after changing it.  :)
