One other thing I have noticed is that I do not like the ground clamp on the Clarke. The one on the right in the picture is the HF clamp, light, easy to squeeze, just enough clamping power to hold a small peice as you tack it. The Clarke clamp on the other hand has an odd outer rim and a pretty heavy duty spring. It just doesn't seem to be as versitile in terms of positioning. One plus, however, the Clarke clamp can be changed with one screw, the HF is hardwired on.
