after search for various belt sander on the Webb , I choose the Makita 9903 . use it be relatively easy , on hand and knee , but with 3M belt , the job -lrb- 900 ft2 -rrb- be not difficult . the sander work very well , have good weight , and do not hardly slow up at all with lot of pressure over knot and irregularity in the wood . long cord be overrated , ext. chord need anyway . but the sand bag be well design , large enough , and easy to empty and reinstall . I do not think there be a better belt sander available at this time . .7 \/ 15\/10 it would be nice if there be a case for it include though .
