Just a bit of a warning ... somewhat recently I came upon a post in a forum (old brain, can't recall where) in which a Bosch Colt user either inured their fingers or came very close to doing so (sorry, old brain, can't recall which) because they were using the Colt router as shown in the the Colt PR20 Operating Instructions, page 13, Figure 13 (hmmm, sounds kind of unlucky). The figure shows the user with the right hand wrapped around the body of the router, and the thumb & pointer finger of the left hand pressing down on the two corners of the router base near the side bit opening (there's actually recessed places that I suspect are specifically designed for this) just an inch or so from the bit itself. The user warned against holding the router in this way.
An alternative suggested was to either use the two-handled Colt plunge Router Base ($86) or something like the Rockler Compact Router Sub-Base with (two) Handles ($30).
