Indeed, as this would not surprise me...I have had a number of negative experiences with eBay "sellers" (crooks).
With regard to the "bulge," in the pictures of the FM2n's display that I have seen (mir.com site), it is a clear bulge with a thin black line on the edge. Thus, it does not "black out" that portion of the field of view. Is this what you had meant? Please correct me if I am wrong, as I will make a buying decision soon, perhaps today.
