Todd, you have to decide if you are going with the whistles and bells approach with lots of expensive store bought add ons or the Router Workshop "Keep it simple" method. Both ways work. Below you will see photos of the fence I built for my first table. The plan was included with two versions of the router table in ShopNotes #1. You can also view the table and fence on PBS by watching The WoodSmith Shop, they use 3 of these tables. Any time you drill holes or mount T tracks in your table for attachments you are limiting their use. By simply clamping your fence or featherboards to the table you have infinite adjustment possibilities. It is also much faster to remove these items from the table for set ups. Custom fences for special jobs need not have the fittings to match up with track mounting systems either, just clamp them in place.
