I am thinking $500. (However, I sometimes have to make my wrench let me pay him for labor.) I think the Xtra has gone up a bit in price since 2006 (like all things bicycle - my bike shop guys warned us it would happen iwth the inflationary forces )

It has been very much worth it. The blender, now, that was a silly thing to get (but tossing my pop-tart money in the jar for it lost me about 5 pounds...) - but the bike... it really *does* change the whole definition of a bicycle.
