Loot Ninja was in Target the other day and noticed they had one Wii Zapper still sitting around. Since no one could find them one for Christmas, they decided they'd drop the $25 themselves and see what the hype is all about.
The Wii Zapper has a very solid construction and was fairly easy to setup. There's a nice cable management system on the bottom section of the Zapper so you don't have to look at the excess cord coming off the Nunchuck. There are two configurations for the Zapper as mentioned in the manual. The first is what you might imagine, with the Wiimote and Nunchuk inside the Zapper. The second involves removing the Nunchuck and using your left hand to manipulate that attachment on its own. Personally, they're all for having everything in one package.
