Found them on sale at my local grocery store while doing some food shopping, they were on sale for $.99 cents each. So I picked up one of each except the WWE Rumblers & Hot Wheels although I may go back for them.
I saw the fruit ninja in a toys r us here in the uk a while back, it was about £4 if I remember correctly. What is it you do with them exactly? They'd be good in kids stockings for Christmas.
It's just a decorated input device. Looks nice, but doesn't really do much other than act like your finger.
