I currently use a Nova four jaw chuck with their woodworm screw and that's been okay.
I'd like to have a dedicated screw chuck and have read positive reviews of the Glaser product here. The threads look sharper than some other screws I've seen and it looks very well made but it's priced a bit high for me..
Any other chucks you would recommend? How about the Craft Supplies screw chuck?
