fyi, as an example, i am selling my old mtb to a buddy for $200, here is what he is getting

specialized stumpjumper m2 frame 18in
rock shox judy xc fork with speed springs (red meduim weight)
shimano xt/lx components
avid speed dial v-brakes / single digit levers
z21 front rim / lx parralax hub
sun rhino mustang a-offset rear rim / xt hub
titec dh monkey riser bar
lock on grips
handful of other slightly blingy parts

i would ask $350 on CL, but you can find deals like this all day long around $200-300 if you know what you are looking for
late 90's high end hardtails are a dime a dozen now, full squish and disc brakes have driven value down to nill
