I have an '08 KM and it is the most comfortable bike I've ever owned. I ran it as a mtb for the first three years and have used it for commuting ever since. Mine has always been set up single-speed (32/18 as a commuter, 32/20 in the woods). I put 40 mm Vittoria Randonneurs on it and it rolls over anything. You should be able to find a used on at a good price on Craigs List.
