I've been thinking about this some more. Unless you're planning to sell loads more Empegs (highly unlikely), and he's planning to sell loads more Empegs (again highly unlikely), then he is not really hurting you in any way whatsover. Sure, it's plagurism, it's not nice, it's taking advantage of your hard work. But maybe you should let it go and take pride from the fact that he thought that your page was so good that he copied the whole darn thing.

As it stands you have virtually no comeback on this - you might persuade ebay to cancel his listing, but I'm sure that they would rather spend their time chasing down real fraudsters.
