I did just what you said you were planning, just finished my MDF fence however I cut some slots in it and attached two hardwood facings so I can adjust the width of the opening. I also cut a U into both the table and the base so I can go deep with the router bit should the need arise. I keep watching the reruns of Router Workshop and see what the guys do with their table, I am just itching to do some of that stuff. I even picked up a spacer fence (3/8's ) when Oak Park still had some left (I see they still have the 1/4 inch left on close out but I think they were down to one, the price is right on them, in fact the stuff they have left is getting almost affordable!) I am going to laminate the hardwood facing tomorrow if I can find the left over from laminating our counter tops a few years back, that was my introduction to using a router and I have been router crazzzzzy ever since. I wanted the hardwood facing so I can replace it should they become damaged, I do do stupid things occasionally. I have pictures of my table posted elsewhere on the site under show your router table but I didn't have the fence ready when I took them. Attached a couple here, I made mine out of an old TV stand I picked up at the State Surplus outlet store, cost me 20 bucks for the stand, all made out of MDF, and 7 bucks for the materials to make my fence, well a few bucks would have to go to one of the woodworking online places where I purchased the kit for building jigs, took the mounting screws and knobs out of that package, nice to have that stuff available since I live out in the sticks where they lumberyard guy looked at me like I was an alien or something when I asked for a sheet of MDF. He tried to talk me into particle board, ya that would make a WONDERFUL fence! Any how it is almost done just have to put a finish on every thing, going to put some Johnson's past wax on the top of the table, several coats, like we used to use in the Army on the barracks floor. Same with the laminate when I have it applied.
