just got myself some of these linky
and they are great, i must have speant more than this on batteries alone! i like this one coz not only does it look cool, but it feeds it's power fromt the wii.
And the bonus that u get 2 sets of rechargable battereis mease no wii user should be without a trusty sword
seroiusly tho, i can't imagine why nintendo haven't brought one of these bad boys out!

I've had one of those for a while now - or one similar at least. They're pretty good.
