Hi, I did a little research for you. It appears that KS indeed made an outlet version of Leslie. Take a look at the auctions on eBay (not my listings).
Black Leslie that appears to be from the full price line (the rim of the interior pocket is leather; no pix of price tag):

Another one from the full price line (tag says PXRU and has only MSRP listed; no interior pix available):

Red Leslie that appears to be made for outlet (tag says WRKU and has two prices and the rim of the interior pocket is plain):

Although the quality for their MFF line is excellent, if MFF is a big factor for you, then you may not want to make a purchase because there is a big chance that you are getting an MFF.
