Man, I don't know what to tell you. The home pad market is pretty far past gone these days.

My suggestion would be to mod/fix it yourself or wait and see what is happening with StepManiaX. It sounds like he (Kyle Ward) might be selling the pads for home use. I'm sure they will be expensive as hell, but they're also supposed to be arcade quality and durability.

However, in regards to your topic: What is wrong with your current pads? Are the panels cracked/breaking? If so, replacing them might not be super difficult. I can recommend some local acrylic guys who should be able to cut new panels for you out of acrylic or lexan. However, It would probably cost ~$50 or more.

Share your pad issues with us and maybe we can help more.

P.S. This thread is old, but useful if you want to "build your own" or even modify your existing pads:

I've always been a fan of the Devout Stealth pads, since their construction is simple and not unlike the Cobalt Flux. Unfortunately, the original site is down, but thankfully it is saved on Web Archive.
