Reading the G7 thread someone mentioned the McKinney-Elliott capo as the ultimate. I had a look at their website and there appear to be a few choices.

Has anyone compared them - what are their pros and cons?
I'd primarily want to use it on my 1 11/16" nut D-28, but also have a 1 3/4" nut 512 that I guess it would be silly to not also take into account.
