I have used the Bosch Colt with a flush trim bit, although I do not have a fancy base. It takes a steady hand to keep from tipping the router and gouging the trim, but if you are careful it gets pretty close.
I usually wind up cleaning up spots with a plane after the router. I use a jack plane instead of a block plane though, as it seems more steady for me. I will sometimes run a strip of blue paint an inch off the trim and let the tail of the plane ride on that. It angles the plane off the tabletop surface, resulting in an imperceptible bevel on the trim, but helping keep the plane iron off the surface. Swinging the tail of the plane out over the tape changes the blade angle too, which is sometimes a good thing.
I really don¡¯t like the trim proud of the surface!
