Which boxing game is best for the wii,?

I would like to know which boxing game is best for fun and getting in shape using the wii. So please tell me which is the most active, how much $$ is it, are certain gloves better than others...specify the game you think is best and the gloves you prefer. I am also curious as to if there is any kickboxing for wii- with attachments one can wear on their feet or ankles to detect leg movement. that would be very cool!
