Extra iPod?

I know I'm a few years behind the trend, but I still don't have an iPod and I'm looking into buying one, not a shuffle, but one with a screen. I looked into getting the iPhone, but it is an extra $30/month on your cell phone bill, so now I'm back to looking for just an iPod. With so many folks upgrading to better iPods and phones, I thought it wouldn't hurt to post a little blog asking if anyone out there had an old one they weren't using that they might want to sell to me for cheap. I've found some for sale on Craig's list, but wanted to try this option first.
