the difference between a table saw with a box trunnion and a c-yoke trunnion. A salesman was explaining the difference between the Jet Deluxe and PM2000 tablesaw and mentioned that the PM trunnion was better than the Jets as it had a box trunnion. I was taking notes but did not ask for clarification on this until rereading my notes.
Since Woodcraft is having a 10% off sale in my area I figured I may take a 1 1/2 hour drive to check these saws out in person. Still leaning toward the Jet ($$) but PM has a good offer worth considering.
