I find it impossible to get through a days work without several. IMO, the router is, for most, the tool that creates the most options for a woodworker. A router can take you from buiiding 1x12 cubes to building furniture. My quiver has grown since this picture was taken, but if the shop was on fire. I'd grab a combo kit on the way out the door and be ready to work the next day. The dado set could burn.
