[quote name='D. Monic']Also, if you want a second mat, Best Buy has the Madcatz Beat Pad for the Cube for $7.99 each. My local store had several, and I bought three. Gamestop also sells a self-branded pad that works on both Cube and PS2. It's a bit pricey at $20, but if you want a basic pad that works with both systems, it's not a bad option.[/QUOTE]
What I did is bought two Mario DDR bundles (one at $37 when Fry's had a sale during the release week), kept one game and both mats, and sold the extra (still sealed) game by itself for ~$90, thus making the whole operation approximately free.
