I have a cast iron wing on a tablesaw, and a lift in a dedicated table. My first preference is one of my homemade rigs as seen the the picture I link to below. With either a Porter Cable 7518 or 690, making an adjustment of a thousandth of an inch is easy by laying it on top of a work table. The big advantages are that it gets absolutely 100% of the dust with no more than a shop vac, and the vacuum keeps the piece pulled up against the fence. We can set up multiple ones, and it takes very little time to set one up or adjust it.
