Unfortunately, Gearwatch is down now. Swamped by newcomers from this thread and another on Stereophile forum. He says next year it will be geared up

to handle the gearwatching throngs.
It is a very cool service, I have been watching tons of gear come up for sale in my own area. Meantime, you can still check your own Craig's List or Ebay, but not as easy as gearwatch.
