I needed to find a used keepall, and this one seems to be authentic, I'm just worried about the wear to the bag. For those of you that would purchase a used Keepall, would you go for this bag? And, if so, up to what price would you say is reasonable for a bag in this condition? http://cgi.ebay.com/AUTHENTIC-VINTAGE-LOUIS-VUITTON-DUFFLE-KEEPALL-BAG-0-99_W0QQitemZ6876618834QQcategoryZ63852QQrdZ1QQcmdZViewItem I appreciate the input!!
