According to some of the members from other than North America, fixed routers can be hard to find. A plunge can do anything a fixed router can do but the reverse is not true so anyone's first router should be a plunge. The only advantage to using a fixed as opposed to a plunge is that the fixed routers have a lower center of gravity. That gives them a better feel and a bit more control when edge routing.
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.
