If I am looking for a fairly low budget Freeride bike, what is best?

Those are all good entry level bikes! People are going to respond to this saying that IronHorse is crap and blah blah blah but they make one HELL of a tough frame. All of these bikes are great, It's just all personal preference. if you can, I would HIGHLY recommend testing these bikes before you choose one, but i know that's not as easy as it sounds. It's all personal preference though. Do you like air or coil suspensin? Do you like the Fox or the Marz forks? Just take your time, read reviews on MTBR.com, do your research, etc, and you should be fine. Good luck though. I hope you find a sick whip!
