iPod Touch (MB528LL) vs. iPod Classic (MC297LL)

I have two iPods. One is an iPod Touch (MB528LL) while the other is an iPod Classic (MC297LL).

The Touch is 8 GB while the Classic is 160 GB.

I've mostly used the Touch, largely neglecting the Classic.

I use the touch mainly for music, but from time to time have downloaded apps including internet-requiring apps. I have also watched a movie or two on the device.

However, I am irritated that my number of songs caps at 1,000. I definitely could use more space considering how often I travel.

I want to sell one of the two devices for a little extra cash. It seems the sale range on the Classic is $200 to $275 and for the Touch it's $100 to $175.

Can anyone help compare/contrast these two models in terms of benefits and negatives unique to each to help me decide which to sell? As I said, I've mainly used the Touch so I'm not very familiar with the Classic. Thanks!
