Why don't you consider buying a NDSL from local retail? Yes it is more expensive but you are guaranteed to get the real deal plus you get warranty and customer support from Nintendo. Plus if you get a NDSL from eBay even if it is a real one it would come with an oversea power adaptor which would probably not work locally anyway i.e. waste of money. The red NDSL with the New Super Mario Bros. bundle that you can get locally is quite attractive.
