To be honest, even though I have been an avid woodworking hobbyist for 40 years, I have never used a plunge router.  Already having a pretty healthy herd of routers, the last thing I need was another router, so instead, I ordered this plunge router base.  I am absolutely amazed at how it changes my previously fixed base routers.  It is almost infinitely adjustable, very well manufactured and has completely revolutionized the inlay work I do.  With the plunge base, it becomes a breeze to take progressively deeper passes, to a predetermined depth with each pass, simply by turning the depth turret.
