I recently purchased a 16GB iPod Touch 2G, and I knew before getting it that it would not charge with my Apple firewire charger that I received way back when I got my iPod Photo. Now, I am looking for a new USB charger that will work with my 2G. I don't want to by the Apple charger, as it is more expensive than I know I can get from iPod accessory companies. What chargers are there available that will work with the 2G? Thanks for you help.
