Replying to New mt. bike fork??

I have a treck 4000 and I was woundering what kind of fork you think would be good (more travel, the better as long as it isnt to soft). Also, if you think it is even worth getting a new fork for it, or if i should save up and get a better bike. also, I definatly wouldnt buy a fork that was more then my bike ($440) and i would mostlikley be looking in the $200+ range, but as long as it is quality, the cheaper the better.
