I recently bought the Wii Zapper and despite the early criticism, I find it's actually pretty well done in my opinion. It works great, but if you have modded the Wiimote so that the back cover sticks out more (Like the Nyko Charge Station and the Batteries and cover make it wider) You'll need to take the cover off in order to lock it down. Other than that I find it quite enjoyable to play with, especially with RE: UC.
