I really enjoy the Konami's PS3 mat to play stepmania. It's like 70$ and you can install a free software / executable to make it work just fine

I got these to work by modding them. The issue was that the arrows could not be active at the same time, so UP+DOWN, RIGHT+DOWN, etc would not work. So, I cut the plastic wire strip, remapped the arrow to other buttons, and used some glue/tape to keep them in place. So, now the arrow keys were the select, start, etc buttons and vice versa. They have been working for over a year now.

Also, I got some think foam workout pads to put underneath them. Win win, since I can use them for both DDR and working out.
