Looking for a bike...
 

Well, right know I have a trek 800, and its pretty bad. The front brake is messed up, the derailleur skips some times, and it has a straight fork. Rather than fixing that (or attempting to), I was wondering what are some decent bikes. The price rang can be about up to 600, maybe a little more. I will probably taking the bike on a lot of trails, and some jumps.
