I've decided that I want to get into mountain biking. I've rode on some pretty technical trails a handful of times with some friends using my fathers bike but i now need and want to get one of my own. I'm currently caught in between getting a 2013 Marin Bobcat Trail for around $700 or a 2013 Trek Wahoo for around $475. I'm not sure what would suit me better or if the Marin would be worth it for me (kind of broke college student)? I'm just under 5'11" the Marin is a 17" and Trek a 19." I'm a noob to mountain biking so any advice would be greatly appreciated.
