I made the awful mistake of buying an iRiver, which didn't stack up and was quickly resold. Now, significantly less stubborn, I've decided it's time to get an iPod. I'm leaning towards 30+gb in storage. So, here are the options I've thought of: 1) A used 4th gen. 40gb player on e-bay 2) One of the ipod photos (though I probably won't use the photo feature much...) 3) a refurb. 3rd generation player being sold now through the Apple web site. I'd appreciate "buying tips" from anyone who has experience with any/all of the above models. The player will be used primarily in the car and for working out. Thanks!
