I know some of the Chinese stuff can be excellent but from watching several reviews they can be patchy. I don't mind paying extra for quality but what I do object to is paying over the odds for what could well be the same Chinese import rebranded. Are there any sensible European/Yank alternatives? Either that or any old British chucks that have plenty of tooling available? I have a Clarkson Autolock S but finding the parts/cutters isn't easy.
