Welcome aboard. I have four Craftsman routers. One I bought in about 1996-7 probably. It died, so bought another in maybe 2003-4, found out later just a solder joint failed, so still need to get on that. Then was given two more. They are all fixed base, kept in the router table, and all work just fine for what I do.
I'd say that it depends on what you want to do for a fixed or plunge. I don't need a plunge, so don't h ave one. If my needs change, I'll get one.

.....Call me a craftsman, artisan, or artistic, and I will accept that. Call me an artist and you will likely get a quite rude comment in return. I am not a @#$%ing artist.
