Clutch question

I just bought a new evo 8 and after 1900 miles the clutch went out, this kinda sucks because i was driving it correctly, but had plans to do a little racing with it. I am having to fight with the dealership and Mitsu Corp inorder to get the clutch warrented. But this kinda leaves a bad taste about the quality of the stock clutch. I am looking aftermarket but have been told by the dealership that if i have trany problems after i put an aftermarket clutch on it then i might not be able to get it warrented. But what do you suggest as the best aftermarket clutch for the car?

Act, or Exedy clutches, depends on what kind you want, not quite sure for Evolutions though
