I wanted to make about about 60 feet of raised panel wainscoting (over 25 panels) for my dining room using 3/4 in. MDF board.  I selected the PC 7518 router because of the power, favorable reviews and other recommendations.  I mounted it in a Bench Dog Pro Lift and mounted that in a Bench Dog ProTop router table and used Freud bits including a 3.5 in. raised panel bit with a back cutter.  This set up breezed through the rail and stile cuts like butter with 1 pass and made very smooth cuts.  The cuts were so precise that no sanding was required where the rails and stiles were joined.  The raised panel bit also generated very smooth cuts but I would recommend 3 passes for safety and a better result.  I was using the set-up on a 15 amp line in the garage (it is a 15 amp tool) with a shop vac to suck up the dust and boy does MDF generate dust.  After blowing the circuit breaker a few times (using the panel cutter), I moved the vac and work lights to a different circuit and that solved the circuit breaker problem.  However the router still shut down if the cut was too heavy or the feed too fast.  It was easily re-set by simply unpluging and repluging the power cord.  Since this was my first major router project, I attribute this to "operator error" hence the 3 pass recommendation for the raised panel cutter.  That cutter really pushes this router to its limits and once I got the hang of it, it performed really well.  However if your looking to do a raised panel with 1 pass in MDF, get a shaper.  The end result is that I have a very happy wife who loves her wainscoting.
