Where to sell a brand new iPod Touch and avoiding getting store credit?

I have an iPod Touch I received as a gift and would like to receive what it is worth back in cash and not store credit.
Selling on eBay and Craigslist, you have to settle for cheaper which is why I ask.
Does anyone know where I would be able to sell my iPod to receive the most money back possible?
It is a 8gb iPod Touch 3rd Generation, still unopened (newest generation). Thanks in advance!
