Bear in mind that U.S. made tools work out relatively expensive by the time you get them here. Worth it for some things, not sure about chisels.
Have you considered Eclipse or Footprint for a start (though there are others) both will be much better value than shopping transatlantic.
You didn't specify size or purpose, but there's also PB Swiss. Mega costly in the U.S. but much better value here, and probably the best out there!
