Shimano cartridge threaded. Don't know if they are made any more, but Ebay is your friend. Make sure you don't get stuck with one of the leftover useless JIS models that have a 27.0 crown race and 30.0 cups.
The brilliant Shimano design helps mitigate the #1 killer of road headsets: false brinelling. Jobst Brandt has written the definitive exposition on this under the heading: "Indexed Steering".
These headsets are also very forgiving in terms of headtube facing issues, and they install easily.
