I use both the Axminster SK 114 (114mm) and the Axminster Clubman 100 (100mm). They are excellent chucks. I prefer the SK114 because of the wide variety of quick change jaws. They are available through Woodturning Store, Deer Park, NY. Axminster has a good website where you can explore the wide variety of jaws for both chucks. I believe the website will refer you to their US dealer mentioned above.
