Is there a best cartridge track force gauge?


I have the Shure gauge, a Technics electronic gauge, and an AR gauge. I have seen many electronic gauges reviewed. Many of these are quite expensive. I would, however, consider one were there an advantage. What is the experience out there?

My Shure gauge may be plated stainless steel, if there is such a thing, but it not unplated stainless steel. I too have never seen magnetic or even marginally magnetic stainless steel, but I guess if you reduce the percentage of chromium it could happen. I am only mildly interested in what the metal is. I am dismayed that anyone would make a cartridge gauge that uses normal steel.
The one I have is ancient, a Shure fromthe 60's or 70's...and it is magnetic as hell!!...When I got back into vinyl some years back, and mounted my new Glider, it snapped together with the scale so tightly that I thought the stylus was stuck in the groove!!.. I was sure my new $750 cartridge was toast!!... When it pulled apart I know my blood pressure went negative, I was so releived.
Time for a new one, and surely non-magnetic.
