Add another vote for the Woodpeckers plates. I've used a Rockler plate and it was fine, but the Woodpecker is a little nicer -- it has the spring-loaded ball bearings to help keep it in place, and it has a nice insert system. (Of course, then you've gotta spend for the inserts, too.) I looked at the Rosseau phenolic plates, but they have an intentional crown in them that I don't think I'd like.
