I don't consider that an unfair price, but as has already been pointed out, price ranges vary a lot.  However, I do consider myself extremely lucky, having only invested $600 net in my current set-up.  I had a 3.0 Mega that became a 3.0 Double, after trading it with a local cycle shop that was down-sizing their product scope.  I also found a local shop going out of business and picked up another 3.0 Double for $200. 
 
I would make sure you have your priorities and preferences identified ahead of time, as timing is the critical piece here.  I missed out on a Brown Sq. O 3.0 Mega based solely on drive time.  I couldn't get there quick enough.
