HowTo Build a Quality DDR Deck
Compu486 writes "In an effort to show that quality dance gaming systems can be done affordably, Inventgeek.com has put together an article showing how
to make DDR systems better than arcade quality for not a lot of cash. Using this
type of system and the free stepmania, hopefully schools
in West Virginia can save some scratch and buy some modern text books."
You can tell that the author is not a seasoned DDR freak like there are out there.
The arcade pads, higher end home ones (cobalt flux), and even the foam pads have raised sections so that you know where you are while you're playing. It's very easy to get lost and start stomping the wrong buttons while playing on heavy (hard) or challenge mode.
