If there are any clash pads at your local EB, they should be $5 for a pair. They are pretty good controllers and have the optional ability to mess around with each other (switching/deactivating buttons, slowing response time, etc..)
Also preowned third-party controllers are $5.99 there, you may find a good brand.
Worked like crap when I tried it with 3 different games (one being Taiko no Tatsujin 5 and the d-pad was very inconsistent in actually registering my pressing it).
