Whats a DSi? anyway.. looks good for a charging cradle, dunno how much it is on fleabay etc. but at least you can see this in real life before you buy it.
This station charges your DSi console and has an easy release mechanism and a LED power indicator.
For ages 7 years and over.
EDIT: Great reviews of it, however.. Charging adaptor not included, so you'll need to use your original one apparently.. meh, prob better off anyway, you really wouldnt want to be using an adaptor which is so inexpensive.
