Sure Grip unit feels much better than Eaton TruTrac did..

Sounds like Dr. Diff's PhD is not in the field of business ethics. He still sells the damn thing.

Actually , he talked me out of buying one, citing excessive side play clearances. He told me he was trying to get Eaton to fix it, but was making shims to correct it. He did not have them ready at the time, and so he listed them as out of stock, even though he did have the units.I have never heard anyone who has actually dealt with him to say anything derogatory about his ethics, in fact, quite the opposite.
