I didn't read everything, so excuse if some of this info is redundant.
If you file an item not as described claim with ebay, the seller will be forced to send you a prepaid shipping label (at his expense) back to him. Then send the item. Once it shows delivered on tracking, ebay will refund you everything you initially paid him (including shipping). You will be out nothing.
