You of course definitely need a 1/2 inch router. I make alot of raised panels and have a Bosch 1617 EVS. It has a fixed base and a plunge base so it comes in and out of the bases easily. You can mount the fixed base to the table and easily take out the motor for use in the plunge base, for easy bit change, etc.
Bits are available from Rockler, Eagle America, Amazon, and so many other sources.
Lowes has a good price on the router combo kit. I'm sure others will also weigh in here and by the way, happy routing.
