I have two routers. One mounted in a router table that I find extremely handy for building furniture. And a second one that I use mainly for large edging projects or with a jig to make mortices for such things as hinges.
I think you are better off sta
ying with one of the smaller routers initially and gain some experience with the tool. Making raised panels with a router can be areal dangerous proposition and is probably best left to either the shaper or even the table saw. A plunge router maight be a
nice compromise if you do a lot of morticing though.
