umm...why wouldn\'t you use a $10 charger from peakcloudy (ebay). I have one of his chargers and it works great. You can see other testimonials on devnet.
The ac charger for most ipaqs also work fine as well. Just pop into your local bestbuy or compusa. All you have to make sure is the 5v regulated. Anything 1 amp or more will do and positive tip.
