Was looking at this the other day for the kids for Christmas and was $55, looked today and down to $40.99. I had a quick look locally and at base.com and this seems to be best price but happy to be proven wrong. Available in all other formats (at different prices) but Xbox One and Kinect seems to be the recommended version as you don't need to hold a smart phone or controller to track movement.
