I bought Fling Smash + Wii Remote from OzGameShop for $39.99
Our family is an avid fan of Wii and we've been slowly adding into our collection of Wii controllers so we have a controller for all our guests. My husband saw this over at Oz Game Shop and immediately bought a couple of the Wii Remote Plus that has built-in motion sensor. It even came with a free Fling Smash game which would be a great combination of game and work-out for our kids who are all not too keen for actual sports. Based on the write up on the game, I'm pretty sure that all of us will be addicted to it and in a competition with each other in no time.
