James,
Is there something about that rack and pinion fence that makes it easier to square up than the standard dual pivot fences? The article mentions the ease of use from being able to adjust it with one hand, but that isn't a huge selling point for me.
It seems like a nice fence design for sure, but it also does take up more room behind the unit, and I'd like to keep mine (in my space constrained "shop") flat up against a wall. However if the rack and pinion is leaps and bounds better from a squaring standpoint, I would consider it.
Thanks!
Brian.
