This video is from The Wood Whisperer and gives an excellent overview of dust control with routers.  This video focuses on the Festool line of routers but it can give you  excellent information if you are thinking about buying a new router.  Dust control is important and these routers have some features that you just have to know about.

Video Overview:

• OF1010, Integrated connector, chip catcher, excellent for edge routing
• OF1400 Dust extraction hood, tool less on/off chip catcher, inline hose attachement
• MFK700 multiple bases and extraction, each base has its own strategy
• OF2200  36o degree spring loaded shroud, 45 degree offset to keep hose out of the way and a snap in chip catcher
