I think I am going to buy this Universal Apple iPod USB Charger Kit for just $2.99. It's everything you need to keep your iPod charged--even on the road. Shipping is also $2.99, but it's still a steal!

Compact design and retractable coil cord are made for easy storage

I'm already thinking Father's Day!
