We only paid for one of these iPods.
We have four iPods between us: 10GB 1st generation (2002), 512K Shuffle (2005), 4GB Mini (2006), and 10GB Touch (2007). The only one I ever paid for was the first. The others are variously gifts from employers or freebies for buying an Apple computer.
The irony is that neither of us care to listen to music through headphones, and seldom use any of them.
