In reply to humptydumpty:
I paid through the nose for some HB ones from South Africa (once import charges had been paid), and then DMM brought out their versions. As far as I can tell, the brass ones are the same from both brands, and the DMM ones look to be better designed to me, in having the wire 'within the profile' of the nut where it goes across the top of it, which seems like it'd help to protect it from damage. Possibly they're lighter too, but it's the wire being protected from abrasion by the shape of the nut which struck me as the biggest improvement on the original design.
I can't speak on which places more easily not having used both.
