heh...i was going to make a thread about getting a bike, but i saw this one in time and stopped myself. Okay..onto my question

I need a bike that's under $500, but i need something that's really lightweight. I won't be doing dirt jumping or anything so it won't need to put up with too much abuse. Also, i only weigh in at 120lbs and i mainly do xc. I want a hardtail, but not rigid. Oh, i saw some posts on K2 bikes and other US manufacturers, but i live in Ontario, Canada and the selection is limited to Specialized, Kona, Norco, Giant, GT, umm...can't think of anything else right now, but yeah..So, suggestions please?

by the way, if you happen to know the weight of any of the bikes, could you please tell me?
