I've got a wii and the wii fit game, I played it loads at first but havn't gotten it out for ages now. It was good though, not sure how much it would help weight loss though I'm happy with my weight so wasn't looking to loose any just wanted the game, most of the exercises are stretches and balance games, not sure how many calories they would burn. The hoola hooping on it really knackered me out though and I did like the step aerobics, keep meaning to get back into playing it because I did find it helped my posture and general flexibility and made me feel a bit more energetic.
Anyone walking past my house can see straight into my living room too so I must have looked like a proper muppet hopping around and waving my arms about in front of the telly. :)
Not sure how much it would cost altogether because my OH runs his own computer game shop and he gave me the Wii and Wii fit stuff, I think the Wii fit board was about £60 when it first came out which to me seems very dear for what it is, it may have come down in price now though and you can get most consoles and things a lot cheaper second hand.
