[quote name='BigFishCarl']I have to disagree.. I once had a 3.0 pad and I took it back for an older version. Its widely known that the 3.0 pads had tons of things wrong with them. Try to find a 2.0 version. Much better quality.[/quote]
When I was looking around for a new dance pad, I found a thread on ddrfreak.com about all the problems with the 3.0
I particularly remember a photo of the thin layer of foam between the contacts on the inside of the foam being completely shredded, leading to ghosting, missed steps, etc.
If you play a lot on heavy, you may want to go with another option, but I can't speak from experience.
