If you do woodworking, you know that sanding is the most dreadful part of any project.  Sanding is usually a dirty, dusty, and unhealthy job.  When my last random-orbit sander got worn out, I replaced it with the 6" Fein MSF636-1.  I also bought the Fein Turbo II dust collector to go with it.  I am so impressed, I just had to sing its praises...
