I'm looking to buy a wall charger for my iPod Touch 2G. Are there certain products to avoid? In other words, are some more vulnerable to a surge or "overcharging" than others? Also, while I'm at it ... does anyone have a good source of reviews for iPod Touch 2G car chargers/docks? My car has a standard CD changer/tape deck. Not the kind with a cable port for mp3 players.
