Gary,
The only metal shear I have direct experience with is the Accu Cutter.
I bought it last year at the ARA show, after looking at a couple of other models also on display. I do not regret my decision one bit, in fact many times I have said to myself, "Self, I'm so glad I bought that cutter. I could not have done this without it".

Unfortunately I have never answered myself so I don't know what myself thinks...but *I* think it's GREAT and highly recommend it.
