I have a Bench Dog Router Table which inserts in place of part of the Craftsman tablesaw extension. It's completely smooth, and has yet to be in the way of anything. In the three or four years I've had it now I've yet to have any problems with broken bits or anything else for that matter.
If you're worried about it sticking out to the left of the saw blade, where most of us do our work, you might consider placing it in place of the right tablesaw extension. Either will work just fine.
