I've been really happy with my 10 year old Trek, I think it's the 600 series? I got it as my 25th anniversary present at work, but I think the street cost then was around $600. I don't do much serious off road riding any more though (mostly stick to rail trails any more due to my aging body falling apart). I don't think my knees could handle a serious "deep in the woods" offroad wreck anymore.
