Maurice,
Here is what I did. I have about 1/2 the space tha you do. I have a Jet LT cabinet saw. I put a jessem Rout-r-lift with Hitachi 3hp vs in the end of them extension table. i have a 52" fence. I was able to get a used Exata fence only through the woodcenteral classifieds. i made an attachment for the fence with removable faces and dust collection. the fence also has micro adjustment, it is the one made by htc for jet. This set up works pretty well as i can make fine adjustment on the fence and router height. I can leave the router set up and still rip to about 36-40 inches. for me a stand alone RT is not an option. I also used the Rockler router switch. If I would just get a camera I wouldn't have to type so much. Maybe my typing will get better. we probally aen't making the choice any easier.
