I am considering swapping out my basic under-table router setup, consisting of a 1/4" thk machined cold-rolled steel plate that has my older Bosch router shoe mounted to it, set into a laminate-topped extension table belonging to the Unisaw. I need to adjust height from below the table, and bit changes involve taking the router out, so I'm looking for more convenience. I have been looking at the Jessem router lifts and Rockler's similar product, and I'm leaning toward the Jessem line. Does anyone have user experiences or insights to offer on these, pro or con?
