If you have the time and money, I would definetly try and make your own metal pad. Thay aren't too too defficult and really worth it because they last for a while and if for some reason they break, u kno how to fix it because u made it lol. It's also a lot cheaper to build onne than to buy one and the people's designs here are really good. I personally am using ddrhomepad's design and it's great. Awesome directions and very simple.
If you don't have the time or much money, just get an ignition pad, but wutever you do, do not buy the hard plastic pads, they are complete crap and try not to buy anything from ebay, it always seems to dissappoint peiople when it coems to ddr. lol, good luck and hope that helps,
Everything happens for a reason. You love DDR for a reason!!
