There's plenty of 1" threaded headsets around. Eprey is not a good place to look for headsets. Tried google?.... try 1" threaded headsets
Tange is a very good brand, moderate and even low priced options. The Passage(alloy or cro-mo) are good, as is the Levin. The Falcon has cartridge bearings.
Chris King is great, but overpriced.
Forget Ritchey. If you need inexpensive, get the Tange Passage cro-mo.
