INCRA is a fine system, I have several things from them and they are all top notch. Is it worth $300 more, depends what you are looking for. If this is a first table and you are just getting your feet wet in router tables, this may be more suited:Been looking at the Incra RT Combo 3 since yesterday.
It costs quite a bit more but looks like a great system.
But is it worth $300 more???
