I bought the rigid combo 6 years ago. I already had a Jet 6" Spindle sander so i have never used the spindles on the Rigid.. It is a handy machine, a little under powered though and mine does vibrate..keep a good sharp belt on it and it will grind fiberglass limbs nicely. After using it for a year..I bought a used Grizzly 6"x80" edge sander and added a pattern sander to the motor end..The Rigid is very light and portable so i still use it on some projects.
