Hi I'm currently staying in the states for a few weeks, and im seriously considering buying the DSlite (@ $129.00 I'd be a fool not to). However i'm worried that I will not be able to charge the battery back home. Has anyone purchased one in the sates, or does any one know if it is OK to charge a US DS in the UK? Do I need to buy a seperate battery charger, or can I chrage it with a USB via the computer. I appreciate any advice you guys can offer. Thanks in advance.
