For the past couple of years, people have sold their used iPods and other music players filled with music on eBay and other auction sites with little notice. But lately, a new breed of seller has popped up, touting like-new iPods jammed full of content -- for prices hundreds of dollars more than the cost of an untouched new iPod.

*A 60-gigabyte video iPod loaded with 11,800 songs, with a starting bid of $799. The iPod alone would cost about $400. "I don't see how it's different than selling a used CD," seller Steve Brinn, a Cincinnati pediatrician, wrote in an e-mail to USA TODAY. "If the music industry asked me not to do it, I just wouldn't do it."

Customers of TVMyPod, launched in November, order an iPod plus the CDs, movies and TV shows they want. TVMyPod then buys the disks, loads them on the iPod, and ships the iPod and all the disks to the customer, says TVMyPod co-founder David Onigman.
