I absolutely love it so far!! It's a great workout. I did it for the first time on Friday, and I was extremely sore on Saturday. It was so fun, though, that I didn't notice how great of a workout was, until I was done with it and breathing incredibly hard! The only downside that I can currentely think of is that it takes a lot of space. I kicked the chair this afternoon!
It was strange to see myself on TV at first, but I got use to it
The camera comes included with the game. I believe Best Buy has it for $49.99, but I'm not completely sure. (My husband works there, so I can use his employee discount.)
If someone already has a PS2 or X Box, and they have lots of space, I'd recommend this to anyone!!
