I see the various jigs that allow plunge routing w/ a Dremel. I have the Black and Decker 3 speed RTX (w/dual overhead cam and underbody neon light kits) and I'm wondering if the jigs are universal, and what brands you might recommend in general. I know Stew/Mac advertises one, but so do the Harry Homeowner places. I want to use it for inlay and routing the rim, and etc. Thanks!
