Looking to buy a hardtail for riding to work and then hitting the trails on the weekends and after work. Want to keep the price around $500, give a $100 or take more. I want something that I can abuse for years to come and not have to return it or upgrade it next week. I've done all my homework and test rode just about everything. I considered Specialized, Gary Fisher, Giant, Jamis, Raleigh, Haro, Kona, and Trek, but for geometry/price/components, I've come down to the Marin Hawk Hill SE or the Canondale F300. Can't decide, both great bikes, so I'm open to suggestions.
