Right now, the going rate for a standard wii package, includes the wii console, a wii-mote, and a numchuck, with the sports disc for 199.00. This is pretty standard across the board at major retailers. Watch Costco if you have a card, as sometimes they have huge package deals that contain extra wii-motes (usually 39.99 each) and numchucks (around 19.99) and often times they have additional games added.
When I purchased ours, almost three years ago, it was 249.99. I bought the Wii Play bundle (49.99) that included an extra wii-mote, and some decently fun games to teach you how the controllers work. Deals are out there, if you look for them. I do suggest buying a travel case for it though, as ours travels quite a bit......
