where to buy clutch fork other than dealer?

been hunting around, searching on the forums. can't seem to find an online source for a clutch fork? just wanted to buy some parts, stick them in my garage, and have them at the ready in case the clutch goes on my car.

looks like my list thus far for a clutch job is:

• clutch fork
  
• ACT street disc and HD pressure plate (SB5-HDMM)
  
• WRX 06+ flywheel
  
• TSK-3 (tranquil sleeve kit)
  

I've found sources for all of the stuff except the clutch fork. On that same note, is there an upgraded/improved clutch fork or something that I can buy so that it won't break as easily as some of the pictures I've seen here?

Thanks.
