I love playing DDR!! I forget that I'm actually getting my heart pumping and getting a workout AND it's addictive. I'm a total clutz so it took me awhile to get from easy mode to standard mode. I bought a cobaltflux pad last year and it's totally worth it if one plans on playing DDR long term. It's not cheap, but if one looks at it as a exersize equipment investment (and already has the gaming system) it's no more expensive that any other decent quality cardio machine.

I will say though that the calorie counter in the game is useless and grossly overestimates the calories burned in a round.
