Last August, as I was getting started in turning, I bought a cheap 4-jaw
chuck with a grip range of about 2-4" and Tommy Bar closure. I'd like to
buy a couple more but don't recall where I bought the first one (online). I
paid about $50 for it, despite being warned off cheap tools and find that
it is more than adequate for what I am doing.

It IS cheap ... there doesn't seem to be any manufacturer identification on
it so I can't even search for it with that term.

Any clues, gang?
