I have two Super nova 2 chucks and several different jaws for them. I would like to pick up a couple more nova chucks and some different jaws as I do not have every jaw set they make but, I notice buying the chuck bodies alone is about as expensive as buying the whole set of their special deal units. Any advice as to where someone could pick up those chuck bodies reasonable or would teknatool consider other jaws with the bodies at reasonable prices? Thoughts?
