They no longer sell the 30gb color and it's not listed on their iPod charts in the stores. They only sell the 20, 40, and 60. All are color. He just happened to find an Apple Store, in Chicago, that had some of the 30's left. (It's the store by where I posted the picture from my ZZ Top tour, of the Audi S4 that got smacked up.)

Apple does not like to call the newer versions 5th gens. They still refer to them as 4g. The difference I have heard about between the older 4g and the newer ones is the color screen and better battery life, which is supposed to be significantly better.

I would pay the extra $20 and get a brand new one. There's nothing like a virgin.
