Like Stick says, you already have routers that will do the job. I've used 3 1/2 hp plunges to do it if I didn't feel like packing 2 routers around. You may still need to dress the edges with a file after you are done trimming. I'm not sure I've ever done a top so well that I didn't think I could improve on it with a little file work. I've known guy at least one guy that didn't have a router and did the whole job with a file. If you aren't familiar with doing that let us know.
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
