While waiting for the Sears photographer to set up all the enhancements she had to try to sell me we found DDR on sale at Sears complete with a pad for $40. That's only $10 off, but it's still a good deal. When we got to the checkout the price was only $20! Super deal! So, if you want DDR dance your way down to Sears today. They had several game system types available.
On a bad note we had trouble navigating the menus. But we did do a little training session and I found it fun. I can't wait to do it in workout mode without the kids around.
