One other factor in selecting is the matter of width of gouge that they accept. The vari-grind 2 says it accepts up to 3/4". The vari-grind says 1/8" to 5/8" and the vari-grind wide says 1/2" to 1-1/8". That creates a bit of a problem for me since I use a 1" gouge a lot and like to use the jig for it. My shop built vari-grind clone handles the range fine, but the wolverine offerings would require me to either buy two jigs make do in some other manner.
Since I was already on the fence, that may be reason enough to shift the scale to sticking with shop built jigs, either the vari-grind clone or a single angle one (or multiple ones if necessary). Given that I may go with a totally shop built setup again. I probably could rework what I have, but while what I have been using has worked okay, it will be a nice chance to do a better job this time.
