I've become a fan of the Incra positioner & fence, and after going through a few tables--wish i'd started with their table and fence set-up. With or without their fence set-up, Incra does a version of both the Jessem Mast-R-Lift (I have) and Woodpecker's PRL-V2 configured to accept their Magna-Lock rings. Quick change, and I especially appreciate the clean-sweep version of the rings as they really help with dust collection. Having used trim rings with little screws to change diameters, then twist-lock, the Magna-lock set-up is a great addition (as is the lift--even though I resisted spending the money for a lot of years...wish i'd done it sooner.) I've not used the Woodpeckers, but the Mast-R-Lift is excellent in both accuracy and ease of use for me.
As for the Incra positioner and fence--the biggest complaint I read from others is the footprint as the positioner extends off the back of the table. I use a 17" on one table and a 25" on another, and when they are extended the rail does stick out. That said, the vast majority of the time i'm using less than 4 or 5 inches of travel, but when I do need to go farther I just roll the table out a bit and have plenty of room. Working in one stall of a garage--space is tight but I don't find the fence extension to be an issue unless I need to use more than normal, and then it's worth every bit of the space issue!!
