Wiimote 8-in-1 weapons kit
Ok, this is getting a bit outrageous. Do you really need an 8-in-1 interchangeable weapons kit for your Wii? Can't you use your imagination?
This kit, from Dragon Electronics, includes an axe, pistol, shield, a pair of daggers and some swords. It's made from soft materials and claims to be "easy to set up and use".
If you desire to have a set of your own, you can pick it up for $28. However, I think your money would be better spent on something else, besides, duct tape and cardboard cutouts would work just as well.
