On Ebay: nice Chris King 1.25-inch THREADED headset
It's not mine, but I thought some here might be interested: there's a nice-looking Chris King THREADED (not threadless!) headset in the rare 1-1/4" size on Ebay right now. No bids and starts at $25. If you have an older Santana or Cannondale you might be able to get a good deal.
