Where can I find an iPod for around 75 bucks that's @ least 16gb?

Is this even possible? The only thing that sucks is that I don’t want to buy off of e-bay or craigslist because I’m not sure if it’s a REAL iPod. And I don’t want to buy something that will be shipped to me.. and I find out it’s broken. Also, I’ve checked e-bay and the only things I found for cheap were the iPod shuffle, and like 1–2gb for that price. Any ideas? Thanks!
