except for the dust collection bag , this be a great belt sander . it be light and managable yet still have more than enough power . the ergonomics be good -lrb- the hand grip area could be a bit bigger -- those of you with bear paw for hand , beware -rrb- . the dust collection bag be not so good though . the bag collect just as much dust as my Porter Cable . but empty the bag be a real hassle . there be no zipper . instead there be a cheap plastic clip . Mine crack after just a few change . -lrb- update : this bag suck . I retrofit a Porter Cable bag . -rrb- also , a sand frame be available for this machine . UPDATE : I first write review in 2004 . my machine be still go strong . I have replace the graphite platen several time . this be a wear item . available from Bosch for about $ 3 each . I have also replace the pulley belt because the belt stretch and be so loose it jump tooth on the pulley . about $ 6 from Bosch . five star for durability !
