These guys sell lots of different pads http://www.ddrgame.com/. I have an Energy thick foam pad and I really like it. I've played a lot on it and it has held up perfectly.
I got one of these http://www.play-asia.com/super-dual-box-pro-paOS-13-49-en-70-qc3.html to replace my old SmartJoy which doesn't work properly with DDR pads on Windows 7. The Super Dual Box Pro is plug and play and has no problem with properly recognizing pad inputs.
