I bought one for christmas and I feel that my brothers wife will want to share it. I am ok with that, but what all goes into moving the wii? Do I just need a 2nd sensor bar for her TV, and to change the wii setting everytime it gets moved? How much effort goes into changing the wii settings when you move it from one tv with one sensor bar to another? Is there a difference among sensor bars or are they universally the same quality? I know with wii chargers there are alot of different kinds, I don't know if sensor bars are the same.
