I am adding Felder DRO to the rip fence as well to my order (and commission to the saw).
my shop is 25¡¯x20¡¯ so I think to save some space and do what David did (and save something like $300-$400). Get the 80cm rip fence with the overhead blade that is capable of cutting 125cm. The overhead for the 700 series is adjustable so I can start with one configuration and if I want I can extend it if needed.
