It may seem frustrating but, there is value in this. You have woodworkers who only use a router for edge treatments, woodworkers that use their router table as a joinery machine and everything in between. The value comes in that the statements are correct for the person making them and can contribute to what you finally decide on.
If I am just putting a bull nose edge on stair treads, a router bolted to a piece of ply and a strip of wood clamped on for a fence will do just fine. If you are into double dovetails with contrasting woods, an indexing fence system will be more capable.
Some folks think the router and router table can do everything including prepare a dinner salad. There are book for the tablesaw like this as well. You need to consider what you will be using your router table for and adjust from there.
I use the router table for edge treatments, mortises, dados, stopped grooves, keyhole slots, sliding dovetails, coping, panel raising and much more. I do not use it as a dovetail machine and although I have a basic Incra indexing system that I thought I would use it has never made it out of the box. Maybe some day.
Maybe I can add a short list of my gotta haves that led me to my current setup:
- Flat, well supported table that extends past the cabinet sides to allow clamping
- Split face fence with t-slots that can accept large diameter bits
- Lift
- Miter slot
- Good dust collection
Things I found I preferred but, could work around:
- A wide variety of throat insert opening sizes to control support area and air flow
- Variable speed on the motor
- A motor switch I can bump-to-stop with my hip
- T-track on the top of the fence
I think if you make a list of your "gotta haves" and "nice to haves" and start percolating over that you will find your way. Enjoy the ride.
